1 mile per minute is 60 miles per hour. 4 miles in 2 minutes = 2 miles per minute 2 x 60 = 120 MPH

[@erembald2927]

Exactly how i did it

[@thenetsurferboy]

4 miles in 2 minutes There are 30 two minutes in 1 hour Speed is 4 x 30 = 120 mph

[@Kleermaker1000]

Rate x Time = Distance. So 60 minutes: 2 = 30 minutes x 4 miles = 120 miles per hour. :)

[@steveneveritt4871]

The way I worked it out in my head was - 4 miles X 5 lots (for total of 10 mins driving) = 20 miles X 6 lots for an hour's worth of driving = 120 mph Same result, just breaks it down into smaller numbers .

[@samswift4921]

120 mph. No paper or pen

Both cars are moving right along!

[@dlkline27]

Simple. If going a mile per minute (60 mph), it would take four minutes to four miles. Doing it in half the time is twice as fast. 2X60=120 provided the law isn't in the area.

[@wingman416]

Algebra was always a tough class for me, as I would have to show my work AFTER doing the simple math in my head. Stupid teacher told the class on the last day that I was her only student to never miss a question on any test or homework she ever had in 40 years of teaching. Lots of smart people in that class didn't care for me much after that proclamation!

[@dlkline27]

@@wingman416 Evidently you are smarter (more intelligent) than the average bear. I have a story too. In study hall, where most did their homework I got into an argument with my best friend over a written problem. He checked with some others and all had the same answer. When we got to class, I was the only one with the right solution. But, nobody got mad at me for it. 😀

[@devonwilson5776]

Greetings. The answer is 120 MPH. Using D=VT, we have 4=2/60V MPH for V=4×30 MPH =120 MPH.

It's a simple ratio. 4/x=2/60 4 times 60 divided by 2= 120

Reminds me of Tommy Lee Jones, who kept getting speeding tickets in his home state of Texas. One day, the Sheriff, who had known the actor since he was a kid, pulled Jones over again. “Tommy, I’m tired of pulling you over and writing you tickets. I want you to get rid of this damn Porsche!” And he did

[@AnneNissen-nk4mh]

I am not sure about the ratio a mile to a kilometer , but it is one mile is ca 1,600 meters .120 times 1,6 makes 120 miles per hour ca 192 kilometers per hour ,if i am not too wrong , and that is very fast.

[@vincentrobinette1507]

I solved both problems in fewer steps. since there are 60 minutes in 1 hour, i just divided 60 by the time driven, and multiplied the distance by that quotient. 60/2=30, 30X4=120. For the second problem, 60/15=4, 4X20=80.

[@Kualinar]

That's an easy one : 120 miles per hour. 1 mile in a minute or 2 miles in 2 minutes mean 60 miles per hour. 4 miles in 2 minutes is twice as fast, so, 120 miles per hour.

[@michaelsanders2655]

It really took that long to get to the answer? I would have figured that out faster in 3rd grade.

[@Ayelmar]

Solved in a couple of seconds at the thumbnail. The answer is 120 mph -- they'd better be on a closed track or on the Autobahn /Autostrada! 4 miles in 2 minutes is 2 miles per minute, 60 mph is one mile per minute, thus 120 mph.

[@Hi-rw8vr]

It’s never specified that the car is going at a constant speed, that would be its average speed.

[@AndreyAngulo]

4 miles in 2 minutes 40 miles in 20 minutes (x10) 120 miles in 1 hour (x3)

[@donfacundo2118]

Solved this in a fraction of a second. I just know the basics, that's all.

[@kennethwright870]

4mi/(2min/60mins per hour), So 4mi/(1/30hr) = 120m/hr

[@stevenjohnson1143]

120 Mph 4 miles in 2 minutes multiply 4 by 30 gets the speed because there are 30 2 minutes intervals in an hour

[@thenetsurferboy]

Exactly what I said before I saw your reply

He had it at the 2 minute mark 2 miles in 1 minute Therefore 120 miles in 1 hour

[@fuzzywuzzy599]

You don't need to memorize a formula you need to understand the relationships. As so many have done in their comment answers. Which long hand is The puzzle time is in minutes you want it in hours. A minute is 1/60 th of an hour. The car has covered 4 miles in 2/60 ths of an hour, the reciprocal of that time ratio is 60/2 and will give the distance in 1 hr so - 60/2 x 4 = 120 miles covered in 1 hr so that's a rate of 120 mph

[@mariano2078]

is 65mph here in New Jersey 120mph is how fast they take your license 🤣

There was a time when the speed limit in Nevada was "Resume speed, thank you" in places. So, it was possible. 🙂

Did I do this right or wrong. Or did I get lucky. 4/Y x 2/60. 2Y=240. Y=120..

[@TheSirRip]

mile a minute = 60mph x2. even a neanderthal can see that.

r=distance/time, 4/(2/60) = 4x(60/2) =4x30= 120 m/hr.

[@russelllomando8460]

2/4=60/x, cross multiple then divided to get x alone so 60 times 4= 240/2=2x/2, 120=x

[@tomtke7351]

Car travels 4 miles in 2 minutes OR 4/2 miles/min = 2 miles/min Combine with 60min/hr = 2miles/min × 60min/hr = 120miles/hr

[@clmkc5393]

S = D/T Speed = Distance/ Time If you know 2 of the 3, you can figure the last unknown. Don't forget to change Time to a décimal. 2 Minutes / 60 = .03333. 4 / .03333 = 120.

[@krunoslavregvar477]

2 miles per minute = =120 mph

[@charlesstraight5499]

One hundred twenty miles per hour.

[@panlomito]

4 miles in 2 minutes??? My guts tells me the car is speeding, so bad... but let us keep it nice. Speed = distance divided by time The distance is 4 miles and the time is 2/60 hour So the speed is V = 4 / 2/60 = 4 x 60/2 = 2 x60 = 120 mph.... bad it is !

[@mr.mxyzptlks8391]

4 miles in 2min=2 miles in 1 minute. Multiply by 60 and we get 120mph. Easy enough, if you can afford the very, very, expensive ticket 😎

Neh... you missed the cherry.

[@ZenWithKen]

Must be an American car, lol. 6.437 kilometers every two minutes. Sixty minutes per hour. 60/2=30. 30x6.437=193 kilometers per hour which is 120 bananas per hour. I hope it's on a race track.

I think I have a better question. If 1 US gallon of gasoline has a mass of 2.85769 kilograms, how much energy (kilowatt hours) is in 1 US gallon of gasoline? According to the EPA it cannot be calculated.

[@thenetsurferboy]

You would simply have to look up the calorific value of the fuel Maybe in Marks Mechanical Engineers Handbook

[@saltydogg]

@@thenetsurferboy Calculating the energy in one US gallon gasoline using elementary arithmetic ( what kids learn in grade 3 or 4 ) you get 12.383 kwh. If you look it up you get 33.7 kwh. The EPA was unable to calculate the value so in 2010 they decided that it should be 33.7 kwh. The EPA is wrong. The calculated value is correct.
