Question

Car A and car B are traveling opposite directions st the same speed. Car A drove for 17 minutes and car B drove for 32 minutes. Car B drove 12 miles more than car A. How fast were the cars driving?

Answer 1

48 mph

Explanation:

Car B drove for 32 minutes. Car A drove for 17 minutes.

32 - 17 = 15

Car B drove for 15 minutes more than car A.

Car B drove 12 miles more than car A.

That means that in 15 minutes, car B drove 12 miles.

speed = distance/time

15 minutes * (1 hour)/(60 minutes) = 0.25 hour

speed = (12 miles)/(15 minutes)

speed = (12 miles)/(0.25 hour)

speed = 48 miles/hour

Answer: 48 mph
