    A passenger train 150 m long is travelling with a speed of 36 km/h. If a man is cycling in the direction of train at 9 km/h, then the time taken by the train to pass the man is

    A) 10 s

    B) 15 s

    C) 18 s

    D) 20 s

    Correct Answer: D

    Solution :

    [d] \[\therefore \] Relative speed of train \[=36-9=27\,km/h=\frac{27\times 5}{18}m/s\] and total distance covered = 150 m Hence, required time \[\text{=}\frac{\text{Distance}}{\text{Speed}}\] \[\text{=}\frac{150\times 18}{27\times 5}=20\,s\]
