Question

You can drive 720 miles in 8 hours on 32 gallons ?

Answer 1

So if you go 720 miles in 8 hours, you would travel at a speed of: 720 miles / 8 hours = 90 miles per hour. So in 1 hour, you would have traveled: 90 miles per hour * 1 hour = 90 miles. (The gallons is irrelevant to the problem)

Answer 2

720 in 8 hours
the ratio is 720 to 8 or 720:8
this can be like fraction as 720/8
simplify it since 8=hours and you want 1 hour
720/8=360/4=180/2=90/1
90  mles in 1 hour on 4 gallons
