Question 304272
A truck enters a highway driving 60 mph. A car enters the highway at the same
 place 13 minutes later and drives 73 mph in the same direction.
 From the time the car enters the highway, how long will it take the car to pass the truck.
:
When the truck enters the highway, the car is 13 min behind the truck
How far can the car travel in 13 min? {{{13/60}}} * 73 = 15.8 mi
:
Let t = time for car to catch truck
:
Write a distance equation Dist = speed * time
73t = 60t + 15.8
73t - 60t = 15.8
13t = 15.8
t = {{{15.8/13}}}
t = 1.2 hrs car catches truck
