Question 989800: Train A leaves the station traveling a constant 35 miles per hour. One hour later, Train B leaves the station traveling a constant 45 miles per hour. Neither train slows down, speeds up, or stops. How long will it take for Train B to catch up to Train A? Answer by ikleyn(52781) (Show Source):
Train A leaves the station traveling a constant 35 miles per hour. One hour later, Train B leaves the station traveling a constant 45 miles per hour
and moves in the same direction. Neither train slows down, speeds up, or stops. How long will it take for Train B to catch up to Train A?
-------------------------------------------------------------------------
Solution
When the train B starts moving, it is 35 miles behind the train A.
The speed of the train B is in 10 miles per hour greater than that of the train A. Hence, it will take = 3.5 hours for the train B to catch the train A.
