A train passes a station platform in 36 seconds and a man standing on the platform in 25 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?  Answers:
A) 877 m B) 165 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 25)m = 375 m. Let the length of the platform be x meters. Then, (x + 375)/36 = 15   ==&gt; x + 375 = 540 ==&gt; x   = 165 m.   Answer: 165 m
