    If a train, with a speed of 60 km/h, crosses a pole 30 s, the length of the train (in m) is

    A)  1000

    B)  900

    C)  750     

    D)  500

    Correct Answer: D

    Solution :

    Speed of train \[=60\,\,\text{km/h}=60\times \frac{5}{18}=\frac{50}{3}\,\,\text{m/s}\] \[\therefore \]      Length of train = Speed \[\times \]Time \[=\frac{50}{3}\times 30=500\,\,\text{m}\]
