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?
Answer & explanation
Correct answer: option 3
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
