Question

Train A of length 115 m crosses a platform of 83 m in 9 seconds. Find the speed of the train.
1. 14 m/s
2. 13 m/s
3. 10 m/s
4. 22 m/s

Answer 1

Correct Answer - Option 4 : 22 m/s

Given:

Length of train = 115 m

Length of platform = 83 m

Formula used:

Speed = Distance/Time

Calculation:

Distance = Length of train + Length of Platform

Hence,

Speed of train = (115 + 83)/9

⇒ 198/9

⇒ 22 m/s
