    At the time train B catches up with train A, they would have traveled same distance from station except it would have taken Train B 15 min less time to get there. **Note: 15 min = 0.25 hr d = r*t 120(t-.25) = 100t 120t - 30 = 100t 20t = 30 t = 1.5 It took 1.5 hrs from time Train A passed station for train B to catch up, or at 11:40
