Trains A and B start simultaneously from X and Y towards each other. They cross after 4 hours. A takes 10 hours to travel XY. Find time for B to travel XY.

1. 6.4 hours
2. 4.8 hours
3. 7.2 hours
4. 6.67 hours

Correct answer: 6.67 hours

Solution

A covers 4/10 of XY in 4 hours. B covers 6/10 in 4 hours. B's speed=6XY/40. B's time for XY=40/6≈6.67 hours.
