The length of a train and that of a platform are equal. If with a speed of 36 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:  A) 752  B) 799  C) 300  D) 750  E) 712
Speed = [36 * 5/18] m/sec = 10 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 10 Ã¨ x = 10 * 60 / 2=
