The length of a train and that of a platform are equal. If with a speed of 126 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is?  Choose the most appropriate option
A) 227  B) 299  C) 1050  D) 750  E) 211
Speed = [126 * 5/18] m/sec = 35 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 35 è x = 35 * 60 / 2=
