Question
What is the time taken by a train running at 9 kmph to cross a man standing on a platform, the length of the train being 360m?
Solution
To solve this problem, we need to convert the speed of the train from km/h to m/s because the length of the train is given in meters.
1 km/h = 5/18 m/s
So, 9 km/h = 9 * (5/18) = 2.5 m/s
The time taken to cross an object is given by the formula:
Time = Distance / Speed
Here, the distance to be covered is equal to the length of the train, which is 360m. The speed of the train is 2.5 m/s.
So, Time = 360m / 2.5 m/s = 144 seconds
Therefore, the train will take 144 seconds to cross the man standing on the platform.
