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?
Choose the correct choice.
A) 37 B) 240 C) 288 D) 267 E) 165
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
