The length of a train and that of a platform are equal. If with a speed of 180 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is? Pick.
A) 1500
B) 266
C) 299
D) 750
E) 261
Speed = [180 * 5/18] m/sec = 50 m/sec; Time = 1 min. = 60 sec.   Let the length of the train and that of the platform be x meters.   Then, 2x/60 = 50 =&gt; x = 50 * 60 / 2=
