A) 12 m/s
B) 24 m/s
C) 48 m/s
D) 96 m/s
Correct Answer: B
Solution :
Length of train \[=\text{12}0\,m\] Length of platform \[=\text{ 36}0\text{ }m\] Total distance \[=\left( \text{12}0+\text{36}0 \right)=480\,m\] Time taken to cover the distance\[=\text{2}0\,\text{sec}.~\] \[\because \text{Speed=}\frac{\text{Distance}}{\text{Time}}\] \[\frac{480}{2}=24\,m/s\]You need to login to perform this action.
