How Many Seconds Will A 500 M Long Train Take To Cross A Man Walking With A Speed Of 3 Km/hr In The Direction Of The Moving Train If The Speed Of The Train Is 63 Km/hr?

Answer»

Speed of train RELATIVE to man = 63 - 3 = 60 km/hr.

= 60 * 5/18 = 50/3 m/sec.

Time TAKEN to PASS the man = 500 * 3/50 = 30 sec.

Speed of train relative to man = 63 - 3 = 60 km/hr.

= 60 * 5/18 = 50/3 m/sec.

Time taken to pass the man = 500 * 3/50 = 30 sec.
