Question 293141: Train A and B are traveling in the same direction on parallel tracks. Train A is traveling 60 miles per hour and Train B at 80 mile per hour. Train A passes a station at 8:20am, if train B passes the same station at 8:35am, at what time will train B catch up to train A?
When will train B catch up with train A?______ Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! a 60 mph 8:20
b 80 mph 8:35
a has a head start of 15 minutes which is 1/4 hr.
in 1/4 hr it goes 15 miles
train b is catching up at 20 miles and hr. so it will catch up in 45 minutes
8:35 +0:45=8:80=9:20 am
We can also write it:
60*(x+1/4)=80x
60x+15=80x
15=20x
15/20=3/4=x
3/4 hr=45 minutes same as above
Train B catches train A at 9:20 am. ANSWER
