A train is running at a speed of 40 km/hr and it crosses a post in 18 seconds. What is the length of the train?  Choose the correct option
A) 190 metres B) 160 metres C) 180 metres D) 120 metres E) 200 metres
Speed of the train, v = 40 km/hr = 40000/3600 m/s = 400/36 m/s   Time taken to cross, t = 18 s   Distance Covered, d = vt = (400/36)× 18 = 200 m   Distance covered is equal to the length of the train = 200 m   answer :200 metres
