A travels time t
B travels time (t-.25hr)
distance = d = rate * time
100 t = 120(t-.25)
you can solve that
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 at 120 miles per hour. Train A passes a station at 5:20am. If train B passes the same station at 5:35 am, at what time will train B catch up to train A?
