A train which is 264 meter long passes a pole in 12 sec. Find out the speed of train?
-
- 80 km/hr
- 80.6 km/hr
- 82.2 km/hr
- 79.2 km/hr
Correct Option: D
Length of train = 264 m
Time taken to cross the pole = 12 sec
Speed of the train, in m/sec = Length of the train/ Time taken to cross the pole
Therefore, speed in m/sec= (264 / 12) m/sec = 22 m /sec
Calculating speed in km/ hour = (22 m/sec ) x 18/5 = 396/5 km/hr = 79.2 km/ hour
