Question 714946
One car travels 45 miles per hour and another one travels 52 miles per hour.
 If they start in the same place at the same time, traveling in the same direction, after how many hours will the faster car be 42 miles ahead?
:
Let t = no. of hrs for them to be 42 mi apart
:
Write a distance equation; dist = speed * time
:
fast car dist - slow car dist = 42
52t - 45t = 42
find t
