Quantitative Aptitude

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

Solution:

Speed of the train = 72 kmph =

{72×5}/18

m/sec = 20 m/sec
Time taken to cross 250 m long platform = 26 sec
Let the length of the train be x meters.
Then,

{x+250}/26=20

⇒ x + 250 = 520, ⇒ x = 270
Thus, the length of the train is 270 m.
