Question

help please
train A and B are traveling in the same direction on parallel tracks Train A is traveling at 100 miles per hour and train B is traveling 104 miles per hour. Train A passes a station at 3:25PM. If train B passes the same staton at 3:55PM, at what time will train B catch up to train A
checking my answer:
If train A is at station at 3:25 at 3:55PM it will have traveled (1/2 times 100) miles
so it is 50 miles ahead of train B
104-100=4 difference in speed
50/4 = 12.5 = 12 hours 30 minutes
(distance apart / difference in speeds)
3.55 + 12 hours 30 minutes it will be 4:25am
so train B
