Question 325143
Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 40 m.p.h. and Train B is traveling at 50 m.p.h.
Train A passes a station at 6:10 p.m.
If train B passes the same station at 6:40, at what time will Train B catch up to Train A ?
-----------------------
In 1/2 hour (640 - 610) train A goes 20 miles (1/2 x 40 mph)
Train B gains on train A at 10 mph (50 - 40)
It takes train B 2 hours to overtake train A (20/10)
6:40 + 2 hours = 8:40
