The length of a train and that of a platform are equal. If with a speed of 54 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 options: A) 752 B) 450 C) 719 D) 750 E) 712
Speed = [54 * 5/18] m/sec = 15 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 15 Ã¨ x = 15 * 60 / 2=
