A bullet train passes a station platform in 36 seconds and a man standing on the platform in 25 seconds. If the speed of the bullet train is 54 km/hr, what is the length of the platform?
Select the correct option.
A) 165 m B) 220 m C) 260 m D) 224 m E) 239 m
A   165 M   Speed = 54 x 5/18 = 15 m/s   Length of the bullet train = (15 x 25)m = 375 m.   Let the length of the platform be x metres.   Then, (x + 375)/36 = 15   --&gt; x + 375 = 540   x = 165m. 165 m
