A train 220 m long is running with a speed of 59 kmph. In what time will it pass a man who is running at 7 kmph in the direction opposite to that in which the train is going?	Choose the correct answer:  A) 7 sec  B) 8 sec  C) 10 sec  D) 12 sec  E) 14 sec
Speed of the train relative to man = (59 + 7)= 
<gadget id="calculator">(59 + 7)</gadget>
<output>66</output>
66 *5/18 m/sec= 55/3 m/sec.   Time taken by the train to cross the man = Time taken by it to cover 220 m at (55/3) m / sec   = (220 *3/55)= 
<gadget id="calculator">(220 *3/55)</gadget>
<output>12</output>
12 sec   Answer : 12 sec.
<result>D</result>
