A bullet train 160 m long is running with a speed of 70 kmph.
A bullet train 160 m long is running with a speed of 70 kmph. In what time will it pass a man who is running at 8 kmph in the direction opposite to that in which the bullet train is going?
Answer/Solution
7.38 sec
Steps/Work
C
7.38 sec
Speed of the bullet train relative to man = (70 + 8) kmph
= 78*5/18 m/sec = 65/3 m/sec.
Time taken by the bullet train to cross the man = Time taken by it to cover 160 m at (65/3) m / sec
= (160 *3/65) sec = 7.38 sec

Speed of the bullet train relative to man = (70 + 8) kmph
= 78*5/18 m/sec = 65/3 m/sec.
Time taken by the bullet train to cross the man = Time taken by it to cover 160 m at (65/3) m / sec
= (160 *3/65) sec = 7.38 sec
