A train passes a station platform in 36 seconds and a man standing on the platform in 22 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?	Pick one:	A) 877 m	B) 210 m	C) 167 m	D) 887 m	E) 265 m
Speed = (54 * 5/18) m/sec = 15 m/sec. Length of the train   = (15 x 22)m = 330 m. Let the length of the platform be x meters. Then, (x + 330)/36 = 15   ==&gt; x + 330 = 540 ==&gt; x   = 210 m.   Answer: 210 m
