A train covers 90 m in passing a standing man. Find the length of the train.
-
- 20 m
- 87 m
- 71 m
- 90 m
Correct Option: D
We know that, the distance covered by a train in passing a pole or a standing man or a signal post or any other object (of negligible length) is equal to the length of the train.
In this case, train covers 90 m to cross a standing man.
∴ Length of the train = 90 m
