The length of a train and that of a platform are equal.If with a speed of 90 kmph the train crosses the platform in one minute,then the length of the train in metres is Choose one:  A) 500  B) 600  C) 750  D) 900  E) 950
2x will be the distance travelled by the train if the length of the train= the length of the platform = x as distance= speed*time   distance=2x   speed in kmph=90   speed in mps=90*5/18   as dist=speed*time   2x=(90*5/18)*(60sec)   on solving x=900mts   ANSWER:900
