Trains a and b sre traveling in the same direction on parallel tracks. Train a is traveling at 40 mile per hour and train b is traveling at 48 miles per hour. Train a passes a station at 7:25pm. If train b pass the same station at 7:40pm, what time will train b catch up to train a?
-----------------
In 15 mins (740 - 725) train A goes 10 miles (40 mph * 1/4 hr)
Train B gains on train A at 8 mph (48 - 40)
10/8 = 1.25 hours
740 + 115 = 855 PM
