The length of a train and that of a platform are equal. If with a speed of 108 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is?	Choose the correct choice from the following choices.
A) 227 B) 299 C) 276 D) 750 E) 900
Speed = [108 * 5/18] m/sec = 30 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 30 è x = 30 * 60 / 2=
