Question 288395: 12. Trains A & B are traveling in the same direction on parallel tracks. Train A is traveling at 40 miles per hour and train B is traveling at 44 miles per hour. Train A passes a station at 5:15pm. If train B passes the same station at 5:45pm at what time will train B catch up to train A? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! train a is going 40 mph for 30 minutes
so it goes 20 miles
train b is going 4 mph faster
so it will take 20/4=5 hours to catch up.
so at 10:45 pm train b will catch up to a
another way to do it
40*(t+1/2)=44t
40t+20=44t
20=4t
5=t
10:45 pm
