The length of a train and that of a platform are equal. If with a speed of 144 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) 757 B) 758 C) 718 D) 1200 E) 738
Speed = [144 * 5/18] m/sec = 40 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 40 è x = 40 * 60 / 2=
