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

270m

210m

340m

110m

Speed =72 kmph = 72×5/18 = 20 m/s
Let length of the train = x metre
Distance covered = 250+x
Time =26 s
250+x /26 = 20

250+x = 26×20 =520

x = 520−250 = 270

Hence, option 1 is the correct answer.
