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
