A train 200 m long is running at a speed of 68 kmph.
A train 200 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?
Answer/Solution
12 sec
Steps/Work
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 200 m at 50/3 m / sec
= 200 *3/ 50 sec = 12sec
Answer : C
= (60* 5/18) m/sec = (50/3)m/sec
Time taken by the train to cross the man
= Time taken by It to cover 200 m at 50/3 m / sec
= 200 *3/ 50 sec = 12sec
Answer : C
