Is this correct???

2. Trains A and B are traveling in the same direction on parallel tracks. 2. Train A is travelling at 100 miles per hour and train B is traveling at 125 miles per hour. Train A passes a station at 5:10 A.M. If train B passes the same station at 5:22 A.M, at what time will train B catch up to train A?

100(t) + 20 = 125(t)
100t + 20 = 125t
25t = 20
t = 20/25 = 4/5 hr X 60 = 48 min
5:22 + 48 = 6:10 they pass each other

Proof
100(4/5) + 20 = 125(4/5)
80 + 20 = 4(25)
100 = 100
