Given:
- Length of the train = 100m
- Speed of the train = 30 km/hr
To find:
- Time taken by the train to pass a man standing near the railway line
Formula:
- Time = Distance/Speed
Calculation:
We need to find the time taken by the train to pass a man standing near the railway line.
- Distance covered by the train to pass the man = Length of the train = 100m
- Speed of the train = 30 km/hr
We know that 1 km = 1000 m and 1 hr = 3600 seconds.
Converting the speed from km/hr to m/s:
Speed = (30 * 1000) / 3600 = 30000/3600 = 25/3 m/s
Using the formula Time = Distance/Speed:
Time = 100 / (25/3) = 100 * 3/25 = 12 seconds
Therefore, the train will pass the man in 12 seconds.
- Length of the train = 100m
- Speed of the train = 30 km/hr
To find:
- Time taken by the train to pass a man standing near the railway line
Formula:

Converting the speed from km/hr to m/s:
Speed = (30 * 1000) / 3600 = 30000/3600 = 25/3 m/s
Using the formula Time = Distance/Speed:
Time = 100 / (25/3) = 100 * 3/25 = 12 seconds
Therefore, the train will pass the man in 12 seconds.
