Select the correct option:
A) 190 metres
B) 160 metres
C) 200 metres
D) 120 metres
E) 250 metres
Speed of the train, v = 40 km/hr = 40000/3600 m/s = 400/36 m/s   Time taken to cross, t = 16.2 s   Distance Covered, d = vt = (400/36)Ã— 16.2 = 160 m   Distance covered is equal to the length of the train = 160 m   Correct answer is 160 metres   160 metres
