tains A and train B are travling in the same dicrtion on a parral track train A is traving 60 mph and train B is traviling 70 mph train A passes a staion at 11.15 am and train B passes the same station at 11.45 am at what time will train B catch up to train A
B takes time t hr
A takes time (t+1/2) hr
they both go the same distance
70 t =60(t+.5)
70 t = 60 t + 30
t = 3 hours
3 + 11:45 = 2:45 pm
