    A train 100 m long travelling at 40 m/s starts overtaking another train 200 m long travelling at 30 m/s. The time taken by the first train to pass the second train completely is

    A)  30s  

    B)  40s 

    C)  50s

    D)  60s

    Correct Answer: A

    Solution :

    Relative velocity of overtaking                 \[=40-30=10\,\,m/s\] Total relative distance covered with this relative velocity during overtaking                 =100 + 200 = 300m So, time taken \[=\frac{300}{10}=30\,s\]
