Question

trains A and B are traveling in the same direction on the parallel tracks. train A is traveling 80 miles per hour and train B is traveling at 88 miles per hour. Train A passed a station at 12:20am if train B passes the same station at 12:35am At what time till train B catch up with train A?

Answer 1

when B reaches station,,A already travelled for 15 mins i.e 1/4 hrs
distance = 1/4 * 80 =20 miles
now for some time t , distance A travels = 80 t
and for same time t , B travels = 88t
B has to travel 20 miles more than A so as to meet it at some point
so we have 80 t + 20 = 88t
so calculate t and find out what time they actually meet.

Answer 2

is it t=10?

Answer 3

t = 2.5 ..how you get 10 ?
