How long will a train 100 m long and travelling at a speed of 45 kmph,...
Given Information:
- Length of the train = 100 m
- Speed of the train = 45 km/h
- Length of the platform = 150 m
To Find:
- Time taken by the train to cross the platform
Approach:
- First, we need to convert the speed of the train from km/h to m/s.
- Then, we can calculate the total distance covered by the train while crossing the platform.
- Finally, we can use the formula for time to calculate the time taken by the train to cross the platform.
Conversion:
- 1 km = 1000 m
- 1 hour = 3600 seconds
Calculations:
- Speed of the train = 45 km/h
- Converted to m/s: 45 * (1000/3600) = 25/2 m/s
- Total distance covered by the train while crossing the platform = Length of the train + Length of the platform
- 100 + 150 = 250 m
- Time taken by the train to cross the platform = Total distance covered / Speed of the train
- 250 / (25/2) = 250 * 2/25 = 20 seconds
Conclusion:
- The train will take 20 seconds to cross the platform.
- Length of the train = 100 m
- Speed of the train = 45 km/h
- Length of the platform = 150 m
