A train travels 100 meters at 70 km hour. A man is running at 10 km per hour in the same direction. What time the train will pass the man?

Question

Accepted Answer

Relative speed of the train
= (70 - 10)
= 60 km/hr
= (60 x 5/18)
= 50/3) m/sec.
∴ Time taken by the train to pass the man
= (100 x 3/50) = 6 sec.
