    A train 280 m long is moving at a speed of 60 km/h. What is the time taken by the train to cross a platform 220 m long?

    A) 45 s                             

    B) 40 s      

    C) 35 s                             

    D) 30 s

    Correct Answer: D

    Solution :

    To cover a distance by train \[=280+220=500\,m\] Speed of train \[=60\,\text{km/h}\]             \[=\frac{60\times 1000}{60\times 60}=\frac{50}{3}\text{m/s}\] \[\therefore \] Time taken by tram \[\text{=}\frac{\text{Total distance}}{\text{Speed}}\text{=}\frac{\text{500}}{\text{50/3}}\text{=30}\,\text{s}\]
