A train passes a station platform in 36 seconds and a man standing on the platform in 24 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?	Options
A) 877 m B) 240 m C) 167 m D) 887 m E) 180 m
Speed = (54 * 5/18) m/sec = 15 m/sec. Length of the train   = (15 x 24)m = 360 m. Let the length of the platform be x meters. Then, (x + 360)/36 = 15   ==&gt; x + 360 = 540 ==&gt; x   = 180 m.   Answer: 180 m
