Question

a train leaves station A at 6 AM and reaches to Station B at 10 AM . Another train leaves station B at 8 AM and reaches to Station A at 11.30 AM . At what time do the two train cross one another ?​

Answer 1

Answer:

The correct answer is 9.24 am

let distance b/w A & B is D

Vab = D/4 Vba = 2D/7

let they meet at T hr after 8 am

D= D/4×(T+1) +2D/7×T

T= 7/5 = 1 hr 24 min

required time = 8 am + 1 hr 24 min

= 9:24 am
