a railway train 100m long is runing at the speed of 50km/hour in what time will it pass pole near the line
To calculate the time it takes for the train to pass the pole, we need to determine the relative speed between the train and the pole.
Step 1: Convert the speed from km/h to m/s.
Since 1 km/h = 1000m/3600s, the speed of the train is:
50 km/h = (50 * 1000) m/3600 s = 50000 m/3600 s ≈ 13.89 m/s.
Step 2: Divide the length of the train by the speed to get the time.
Time = Distance / Speed
Time = 100m / 13.89 m/s ≈ 7.20 seconds
Therefore, it will take approximately 7.20 seconds for the train to pass the pole.
