NO! He teaches TWO things in every lesson. 1) how to solve the answer to THIS problem whatever it is, 2) how to solve ANY PROBLEM that uses this principle. Like I posted the first time someone bitched about this "he wastes my time or stretches things out". GIVE a man a fish (fine) or, TEACH A MAN TO FISH(BETTER!) My Algebra1 teacher used to warn us "don't think you're going to pass this class thinking oh 3X= 6, this is easy" cuz things are gonna get way more complex! and I ended up having to take it again in the summer! I WOULD ADVISE THIS TEACHER TO POST AN EXPLANATION AT THE TOP OF EVERY LESSON "WHY WHAT I DO MAY SEEM LIKE OVEREXPLAINING....BUT ISN'T!

Don't commit that formula to memory but understand what that formula means and why it is so. Then you don't need to memorize but you can work out this and similar formulas whenever needed. This seems to be unnecessarily complicated video to solve a simple problem. Students are likely to think that this is a very complex problem.

Greetings. Wow. This vehicle is absolutely blazing. I can't believe that this vehicle will have traveled approximately 7 miles in 5 minutes. Wow. The answer is determined as follows. We use the formula D = VT where D= distance travelled, V = velocity in MPH, and T = time taken. Now we will convert 5 minutes to hour by dividing 5 by 60 to get the the time of travel. Thereafter, we multiply the conversion rate by the velocity to get (80×5)/60 miles = 400/60 miles = 6.666666 miles, approximately 6.7 miles. This is insanely fast. That is a very far distance to travel in 5 minutes.

It's not a mistake, you just have to keep track of the units. Distance = Rate × Time is absolute; therefore, 80 miles/ hr × 5 minutes is a distance. It is exactly 400 mile·minutes/hour. Now if 60 minutes = 1 hour then 1 hour/60 minutes = 1. Hence 400 mile·minutes/hour = 400 mile·minutes/hour × 1hour/60minutes = 40/6 miles = 6 2/3 miles. ◼

At 80mph you would be traveling 1 and a third miles every minute. In 5minutes at 60mph distance travelled = 5 × 1 mile In 5minutes at 80mph distance travelled = 5 × 1 and a third miles = 5 + 5/3 miles = 6 and 2/3 miles =6.667miles

5 min=1/12 of an hour, now divide 80 by 12 and that equals 6.66R or rounded 6.67.

80mph /60 minutes = 1.33. 1.33 x 5 minutes = 6.67 miles

Around 6.5 miles off the top of my head. 20 miles in 15 min...so a third of 20.
