Question

Two commuters leave the same city at the same time but travel in opposite directions. One car is traveling at an average speed of 63 miles per hour, and the other car is traveling at an average speed of 59 miles per hour. How many hours will it take before the cars are 610 miles apart?

Answer 1

They are traveling in opposite directions so the combine speed is 63 + 59 = 122 miles per hour.

Divide total Distance by total

Speed:

610 / 122 = 5

It will take 5 hours
