    A train travelling with a speed 60 km/h catches another train travelling in the same direction and then leaves it 120 m behind in 18 s. The speed of the second train is

    A) 26 km/h

    B) 35 km/h

    C) 36 km/h

    D) 63 km/h

    Correct Answer: C

    Solution :

    [c] Let speed of another train = x km/h \[\therefore \]    \[(60-x)=\frac{120}{18}\times \frac{18}{5}\] \[\Rightarrow \]            \[60-x=24\] \[\therefore \]    \[x=60-24=36\,km/h\]
