a railway train 100 m long is runing at the speed of 50km/hour in what time will it pass pole near the line?
To find the time it takes for the train to pass a pole near the line, we can use the formula:
Time = Distance / Speed
Given:
Length of the train = 100 m
Speed of the train = 50 km/hour
First, we need to convert the speed from km/hour to m/second:
1 km = 1000 m
1 hour = 3600 seconds
So, 50 km/hour = (50 * 1000) m / (3600 seconds) = 50000 m / 3600 seconds ≈ 13.89 m/second
Now, we can substitute the values in the formula:
Time = Distance / Speed
Time = 100 m / 13.89 m/second
Time ≈ 7.2 seconds
Therefore, it will take approximately 7.2 seconds for the train to pass the pole.
