A bullet train passes a station platform in 36 seconds and a man standing on the platform in 22 seconds. If the speed of the bullet train is 54 km/hr, what is the length of the platform?
Answers
A) 240 m  B) 220 m  C) 260 m  D) 224 m  E) 210 m
A   210 M   Speed = 54 x 5/18 = 15 m/s   Length of the bullet train = (15 x 22)m = 330 m.   Let the length of the platform be x metres.   Then, (x + 330)/36 = 15   --&gt; x + 330 = 540   x = 210m. 210 m
