Answer 1

Answer:

I think there is an error in the question:

Here is the correct question:

A train leaves a station A at 7 am and reaches another station B at 11 am. Another train leaves B at 8 am and reaches A at 11.30 am. The two trains cross one another at

A. 8:36 am

B. 8:56 am

C. 9:00 am

D. 9:24 am

Solution...

We will assume the distance to be D between A & B

Vab = D/4

Vba = 2D/7

D= D/4*(T+1) +2D/7*T

T= 7/5 = 1 hr 24 min

8 am + 1 hr 24 min (this is the time required)

= 9:24 am
