    A 120 m long train is travelling at a speed of 90 km/h it will cross a railway platform 230 m long in

    A)  \[4\frac{4}{5}s\]                      

    B)  \[9\frac{1}{5}s\]

    C)  \[10\,\,s\]                                 

    D)  \[14\,\,s\]

    Correct Answer: D

    Solution :

    Distance travelled by a 120 m long train to cross a platform 230 m long \[=120+230\] \[=350\,m\] And speed of train \[=90\,k\text{m/h}\]             \[=\frac{90\times 5}{18}=25\,m/s\] Thus, time taken \[=\frac{350}{25}=14\,s\]
