A 180 m long train crosses a man standing on the platform in 6 seconds. What is the speed of the train?
Answer & explanation
Correct answer: option 2
180 m long train crosses a man standing on the platform in 6 seconds
Distance = 0.18 km
Time = 6/3600 = 1/600 hours
Speed = 0.18/(1/600) = 0.18*600 = 108
The correct answer is Option (2) → 108 km/h
