Problems on Trains - Data Intensity 1 Questions and Answers Discussion Page.

5.	A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?
	A.	120 m
	B.	240 m
	C.	300 m
	D.	None of Above

Answer: Option B

Explanation:

Speed = 54 x 5 m/sec = 15 m/sec.

18

Length of the train = (15 x 20)m = 300 m.

Let the length of the platform be x metres.

Then,	x + 300	= 15
	36

x + 300 = 540

x = 240 m.
