    A train 110m long is running with a speed of 60 km/h. What is the time in which it will pass a man who starts from the engine running at the speed of 6 km/h in the direction opposite to that of the train?

    A) 5 s                               

    B) 6 s

    C) 10 s                             

    D) 15 s

    Correct Answer: B

    Solution :

    Since, train and man running opposite to each other. \[\therefore \] Relative speed \[=60+6=66\,\text{km/h}\]             \[=\frac{60\times 5}{18}\text{m/s}\] \[\because \]       \[\text{Time=}\frac{\text{Distance}}{\text{Speed}}\] \[\therefore \]      \[\text{Time=}\frac{110}{\frac{66\times 5}{18}}=\frac{110\times 18}{66\times 5}=6\,s\]
