Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 60mph and Train B is traveling 80mph. Train A passes a station at 6:10pm. If train B passes the same station at 6:35pm at what time will train B catch uo to train A .
...
let x=travel time(min) train B catches up to train A
both trains traveled the same distance
travel time for train B=x
train A traveled 25 minutes less=(x-25)
distance=speed*travel time
60x/60=80(x-25)/60
x=(4x-100)/3
3x=4x-100
x=100 minutes
ans: train B catches up to train A in 100 minutes
