You can put this solution on YOUR website! Train A and B are traveling in the same direction on parallel tracks. Train A is traveling at 40 miles per hour and Train B is traveling is 60 miles per hour. Train A passes a station at 11:10PM. If Train B passes the same station at 11:20Pm, at what time will train b catch up to train a?
-------------------
In 10 minutes, Train A goes 40 mph*10/60 hr = 20/3 miles
Train B is moving 20 mph relative to Train A.
20/3 miles/20 miles/hour = 1/3 hour = 20 minutes.
11:20 + 0:20 = 11:40
