Description : A train, 1800 meters long running at the rate of 204 km/hr will cross a platform in: A) 16 B) 32 C) 45 D) 64
Last Answer : ANSWER: B Explanation: Speed of the train = 204 km/hr. We have to find the time in seconds, so convert the speed in the unit of m/sec. Therefore 204 km/hr = 204 x 5/18 m/s = 1020/18 m/s Length ... m/sec Time = distance/speed = 1800/(1020/18)sec = (1800*18/1020)sec = 32 sec (approx.)
