A train 120 m long is running at a speed of 68 kmph. How long does it take to pass a man who is running at 8 kmph in the same direction as the train?	Choose the correct choice from the following options:
A) 7.2 sec B) 9.3 sec C) 12 sec D) 15.2 sec E) 18 sec
Speed of the train relative to man = (68 - 8) kmph   = (60* 5/18) m/sec = (50/3)m/sec   Time taken by the train to cross the man   = Time taken by It to cover 120 m at 50/3 m / sec = 120 *3/ 50=
