Travel question

Question

A truck enters a highway driving 60 mph. A car enters the highway at the same place 10minutes later and drives 67mph in same direction. From the time the car enters the highway, how long will it take the car to pass the truck 

Answer 1

60 mph leaves

then 10 minutes later 67 mph leaves,

when does 67 mph catch up?

60T = 67(T-10) where T = time measured in minutes

60T = 67T - 670

7T = 670

T = 670/7 = 95 5/7 minutes = 1 hour & about almost 43 minutes
