A train of length 260 meter running at a speed of 72 km/h. Find the time taken to cross a man standing on the 260m long platform?

13 seconds

Speed of train = 72 × \(\frac{5}{18}\) = 20 m/s

Distance travel to cross a man is equals to the length of train.

Therefore, D = 260 m

Time to cross = \(\frac{Distance}{Time}\) = \(\frac{260}{20}\) = 13 seconds
