Question

A train 108m long moving at a speend of 12m/s crosses a 112m long train coming from the oppositedirection in 11 secons qhat is the speed of the other train

Answer 1

Answer:

The speed of the other train is 8 m/s

Explanation:

Given, the speed of the first train = 12 m/s

Let the speed of the other train be v m/s

Then speed of the first train relative to the second train = 12 + v

The first train covers total length of 108 + 112 = 220 m with speed 12 + v in 11 seconds

Therefore, using distance = speed × time

220 = (12 + v) × 11

or, 12 + v = 220/11 = 20

or, v = 20 - 12 = 8

Therefore, the speed of the other train is 8 m/s

Hope this answer is helpful.
