Question

Train A & B are traveling in the same direction on parallel tracks. Train A is traveling at 40 mph & Train B at 48 mph.

Train A passes a station at 2:20 am. If Train B passes the same station at 2:35 am, what time will Train A catch up to Train A?

Answer 1

OOps, I meant train B catch up to train A

Answer 2

Train A leaves 15 minutes = 1/4 hour earlier than train B (from the station)
After x hours the distance traveled by both train are
Distance train A= (1/4)(40)+40x
Distance train B= 48x
Train B catch up train A if the two distance are equal
\(10+40x=48x\)
\(8x=10\)
\(x=5/4\) hour = 1 hour 15 minutes
So Train B catcch up Train A at 3:50 am
