Algebra Word Problem: Distance, Rate, and Time

[@venero9]

Thanks for the video. I was really stumped with this equation in my mathbook. The answer key only tells you so much. Working through it is priceless.

[@PaulBilski]

I was about to have a meltdown, then this... this right here saved me..

[@GooseDood]

Wow this was so helpful, my Algebra 2 teacher isn't very clear when teaching so it's nice to be able to rewind here. She also skips steps very often and it's confusing. Thanks a lot.

[@oreion69]

Thank You. Whenever I watch your videos, you always drive the point home! =D

[@patrickjmt]

@venero9 yep, always a few steps left out in the answer keys. always nice to see someone go through it all!

[@15marianml]

patrick! i got exempted in algebra because of you... :)) thank you so much for your BIG help!

[@katierobey-bhamani4435]

thank you this is the exact problem I was struggling with thank you!! test tomorrow!!

[@iranianboy123]

You make it look soooo easy man im struggling with world problems like no other thing in the world

[@patrickjmt]

@iranianboy123 they are tricky since they are not mechanical. they always take a bit of time to sort out.

[@bassman1201]

I appreciate this video very much; it is done quite well and also it is explained well. This is a kind of problem if you mess up one step, your done, and you make it easy. Thanks! Algebra 1 student

[@91dgross]

So all i did was take 10 mph and multiplied it by 5 hours as rate times time = d. and i got 50miles. then i added up the two distances of 24 + 24 and got 48. 50-48= 2miles. Distance is directly proportional to speed so long as the time is constant which in this case it is. So i got my answer in about 3 or 4 steps lol. Not saying i'm better than you, but common sense can be used to solve most of these problems

[@cabrera052010]

Thank you so much for posting this video this is so helpful :) You're amazing!

[@gellybelly2]

That's a nice twist on a d=rt problem. Great explanation too.

[@3rdandlong]

Thank you Pat. Yes, a more simplified version of D=R.T for those of us with brains that have slow memory.

[@fadhll]

You made the world so easy :) Thanks Patrick.....

[@TheAirjordan1997]

thank u patrick. i was having trouble and u helped alot. thanks

[@daydreamer088]

Thanks for the vid. I admit that im too slow when it comes to numbers but thank you for real. I think Im loving math already

[@angeliquaserenity5009]

Just a small quip: While there isn't technically a negative velocity, the negative and positive values tell us whether or not we are going left or right on our number line with regards to velocity. Imagine a car going backwards on a number line. The car would be headed in a negative direction on the number line.

[@mandingo609]

hey, this was good tutorial. for GRE word problems with an added variable, and quadratic expression Thanks

[@brco2003]

I'm a straight A student whose doing multivariable calculus and I still can't do any of these types of problems. Thanks for clearing it up!

[@jitterbop]

That was fun to watch. D=r(t) is one of my favs.

[@patrickjmt]

perhaps you can post a video where everything is broken down specifically enough

[@thevanamacha]

Omg! You just totally saved my mathematically challenged life. Thank you for explaining the key to d = r . t :)

[@qinshihuang960]

lol

[@patrickjmt]

learning to read a math textbook is a fine art i think; i had to get used to them as well. however, KEEP READING! in my opinion, it is one of the single best things i did. i mean, in what class beside math (the hard one) would someone not read the book (duh); but i think tons of people do not (most in fact).

[@patrickjmt]

thanks gb!

[@gabrielaalmeida537]

Thanks a lot ur video been so helpful for me i hope u keep doing some more videos like this one

[@carlosketchbook]

Great vid! Easy to understand

[@DB5tothehive]

Dang, couldn't get anything out of this vid. I'm able to comprehend many things that get thrown at me mathwise so far. However, when I hit word problems, my mind straight BLANKS.

[@pinks0210]

do you have any video related to time and work problem???

[@VRMorrigon]

I don't understand how you decide to subtract 500 from both sides and then divide both sides by -5. Is there a general rule for determining these things? These videos are fantastic, thank you!

[@speakerstereo]

hey thanks alot man, it's such a helpful video

[@yyyy2999]

im shocked i got the exact question in my book :OO so happy

[@steelcantuna]

I actually set-up the formal for this equation correctly: like the way you show it at the bottom of your page @ 4:24. I didn’t have any REAL IDEA as to how to go about solving it though. Is there a name for this type of equation (kind of like there are names for polynomials, or quadratics)? I need to look up similar equations (not necessarily WORD PROBLEMS) to practice. Thanks

[@melissasedam2155]

Also when you multiply both sides is it just a rule? Or because i thought you empty one side both are cluttered... is this a mistake on your behalf.????? When you inverse something its to empty side so the left should be cwancelling out the denominators right?...

[@candyloverinthehouse]

i have a test tomorrow on this.AND I DONT HAVE NOTES. SO... thanks! >3

[@gspken]

can you give an example about a ship travelling at a certain speed catching up with another ship, were distance is not in the problem, only the rate and time

[@Goombanegro]

@patrickJMT ok in the equation what if they added seconds, for the time?

[@josephmartin478]

Thanks for the video! Very helpful!

[@watshakingbacon]

thank you so much! great videos!

[@lafyguy]

i need help with this question (finding depth of a well.) A stone is dropped into a well,and the time it take to hear the splash is 4sec. Find the depth of the well . Assume that the speed of sound is 1100ft/sec and that D= 16 t^2 is the distance D of an object falls in (t) seconds.

[@chrisylthemissile26]

you make it look so easy...

[@Zee1]

could you help me with this problem?? I tried using your method and i didn't get the right answer. A truck travels 350 km to a delivery point, unloads, and, now empty, returns to the starting point at a speed 8.00 km/h greater than on the outward trip. what was the speed of the outward trip if the total round-trip driving time was 14.4 h?

[@pattitice2844]

Excellent video! However, I understand the entire concept of the equation with the exception of distributing 10-C & 10+C to both sides. My understanding of 10-C & 10+C applied to the left side of the equations is great. But on the right I see that the10-C & 10+C cancel out, in which I'm left with 10+C & 10+C how does that equate to 24(10-C). How do two negatives become a positive?

[@Iamseunsule]

Hello, I still didn't understand this. What should i do? Can make one a little easier?

[@MegaDannyboy1977]

Bonus,can't wait till I get that friggen good at it. Very helpful when your stumped. Cheers DANIEL west oz 2012.

[@killerkite333]

thanks a lot ^^

[@nfal445]

My brain just exploded and covered my computer.

[@lisapowwow]

very helpful. thanks!

[@miiluve]

i didn't know whre that was going; you are good

[@waterjob]

Okay please help me if i am wrong but total 48miles=10mph x 5 hours which is wrong because 10 x 5 = 50 but however we are not factoring in the current so 50 - 48 = 2mph which is the current it just is so much easier that way or am I wrong HELP ME IF I AM WRONG!!!!!!

[@lakersmagik]

Moe jogs past the library at 9:00Am going 4mph. twenty min. later, curley runs past the library at 6mph following the same trail. What time will curley catch up to moe?

[@kitzykyasa]

oh yah!!!!youtube for reviewer!! :)

[@SammieW23]

u r really smart. :)

[@patrickjmt]

@sskdb : )

[@fjordtru]

Im stressed, i need a tutor that can help me, Patrick, thanks for the video but i stil don't understand. Good video though : )

[@catfishjack8169]

thank u

[@patrickjmt]

you cant please everyone all of the time

[@daemon3spade]

i hate math but i love u

[@jadriesg]

Thanks !!

[@lordsheepidk6301]

Thanks

[@harrythehamster72]

How does it equal 5? And it did not help me at all.

[@adnanmo9315]

thanx a lot

[@444zane3]

okay im not saying this to brag lets clear that up. im in advanced math classes by like 2-3 years. and im probably the average guy in my advanced class. and even the smarter people of the class get stuck on word problems. schools dont focus on word problems that have to do with this kind of stuff enough. in pre algebra there were the simplest word problems ever. and in algebra 1 they get like 10 times as hard.

[@melissasedam2155]

At approximately 6 :10 in this video I got scared of your teaching. Please educate me on why. I see we are doing the inverse to the fractions which are ttechniquely divition. But 5(10-c)(10+c) how are you getting the parenthesis befor distributing... the 5 the answer changes drastically. I hope you don't mind answering my question because I'm a mom who hopes to achieve a comfy survival of a career i choose. So how come your using pemdas but distribution isnt mentioned in pemdas.... perhaps the multyplying is why. I have watched various videos I am still stuck. I am married I do not what your flirtation your wife can rest assured. Much appreciation, Young and desperate mom, Melissa

[@adamhawhee8379]

if the boat was in still water there would be no current, but sense the question is asking for the rate of the current, why the hell does the question contradict itself by saying the boat is in still water???

[@friedchicken5970]

its nice but it would have been better if you went straight to the point...

[@Stackthatcheeze32]

thanks fam

[@qinshihuang960]

do u know what fam is

[@WhoppingPP528]

Thanks man .. :D

[@3rdandlong]

I understand what you are doing. But you are not explaining how to break down equation specifically enough--in the early stages.

[@Casey5693]

I think I understand it.

[@lakersmagik]

need help don't know where to start?

[@jordanr7777777]

This shit is so hard

[@ismile4fun13]

Ahhhhhhhhh I have a head ache

[@SammieW23]

and u hav nice handwriting 4 a guy.

[@budgerigar42]

He's left handed.

[@rancid554]

Y r word problems sooo complicated!!!

[@mrglenn66]

all i ca say is wtf?

[@littlee300]
