A train 300 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 most appropriate option:  A) 5 sec  B) 9 sec  C) 12 sec  D) 15 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 300 m at 50/3 m / sec   = 300 *3/ 50=
