Two trains are moving with equal speed in opposite directions along two parallel railway tracks. If the wind is blowing with speed `u` along the track so that the relative velocities of the trains with respect to the wind are in the ratio `1:2,` then the speed of each train must be

A

3u

B

2u

C

5u

D

4u

Text Solution

Verified by Experts

The correct Answer is:
a
`3u-u=2u` Ratio 1:2
`3u+u=4u`
Hence speed is 3u.
