Question 341696: trains a and b are traveling in the same direction on parallel tracks. Train a is traveling at 100 miles per hour and train b is traveling at 104 miles per hour. Train a passes a station at 5:15 pm. if train b passes the same station at 5:45 pm, at what time will train b catch up to train a?

When B passes the station A will be 100*.5=50 mi ahead of it.
Difference in speeds 104-100=4.
50/4=12.5 hrs before train b catches up.
5:45 PM + 12:30 = 6:15 AM time when B catches A.
