A train, 500 metre long, running at a uniform speed, passes

A train, 500 metre long, running at a uniform speed, passes a station in 35 seconds. If the length of the platform is 221 metre, the speed of the train in km/hr is

Speed of train =	Length of platform and train
	Time taken in crossing

=		221 + 500		metre/second
		35

=		721		metre/second
		35

=		721 × 18		kmph
		35 × 5

= 74.16 kmph
