Question
A 180 m long train crosses a man standing on a platform in 20 seconds. What is the speed of train (in kmph)?Options241832.428.6
Solution
To find the speed of the train, we need to use the formula:
Speed = Distance / Time
Here, the distance is the length of the train, which is 180 meters, and the time is 20 seconds.
So, Speed = 180 m / 20 s = 9 m/s
But the options are given in km/h. To convert m/s to km/h, we multiply by 3.6.
So, Speed = 9 m/s * 3.6 = 32.4 km/h
Therefore, the speed of the train is 32.4 km/h.
