    A train of length 110 m is running at a speed of 60 km/hr. In what time will it pass a man who is running at 6 km/hr in the direction opposite to the train? 

     A.   8 sec
     B.   10 sec
     C.   6 sec
     D.   15 sec

    Answer: Option C 
    Explanation:
    Distance = 110 m
    Relative speed = 60 + 6 = 66 km/hr = 66 x (5/18) = 55/3 m/s

    Time taken = Distance/Speed = 110/ (55/3) = 6 sec
