    A train 125m long is running at 50 km/h. In what time will it pass a man, running at 5 km/h in the same direction in which the train is going?

    A)    15 s     

    B)  10 s 

    C)  12 s    

    D)  14 s    

    Correct Answer: B

    Solution :

    Speed of the train relative to man\[=(50-5)km/h\]= 45 km/h \[=\left( 45\times \frac{5}{18} \right)\,\,\text{m/s}=\frac{25}{2}\,\,\text{m/s}\] Distance covered in passing the man = 125 m \[\therefore \]Time taken \[=\frac{125}{(25/2)}\text{s}=\left( 125\times \frac{2}{25} \right)\text{s}=10\,\,\text{s}\]
