A train, 300m long, passed a man, walking along the line

A train, 300m long, passed a man, walking along the line in the same direction at the rate of 3 km/hr in 33 seconds. The speed of the train is

If the speed of the train be x kmph, then relative speed = (x – 3) kmph.

or (x – 3) ×	5	m/sec
	18

⇒ 5400 = 33 × 5 (x – 3)
⇒ 360 = 11 (x – 3)
⇒ 11x – 33 = 360

⇒ x =	393	= 35	8	kmph
