A bullet train passes a station platform in 36 seconds and a man standing on the platform in 24 seconds. If the speed of the bullet train is 54 km/hr, what is the length of the platform? Choose the correct choice from the following
A) 240 m  B) 180 m  C) 260 m  D) 224 m  E) 239 m
A   180 M   Speed = 54 x 5/18 = 15 m/s   Length of the bullet train = (15 x 24)m = 360 m.   Let the length of the platform be x metres.   Then, (x + 360)/36 = 15   --&gt; x + 360 = 540   x = 180m. 180 m
