A train moving at a rate of 36 km/hr. crosses a standing

A train moving at a rate of 36 km/hr. crosses a standing man in 10 seconds. It will cross a platform 55 metres long, in :

Speed of train = 36 kmph

= 36 ×	5	= 10 m/sec
	18

Length of train = 10 × 10 = 100 metres

∴ Required time =	100 + 55
	10

= 15	5	= 15	1	second
	10		2

= 15.5 seconds
