A train 200 metres long is moving at the rate of 40 mph.in how many se...
Given:
- Length of the train = 200 meters
- Speed of the train = 40 mph
To find:
- Time taken by the train to cross a man standing near the railway line
Formula:
- Speed = Distance / Time
Conversion:
- 1 mile = 1609.34 meters
- 1 hour = 3600 seconds
Calculation:
- The speed of the train is given in mph, so we need to convert it to meters per second (m/s).
- Speed of the train in m/s = (40 * 1609.34) / 3600 = 17.881 m/s
- Speed = Distance / Time
- Time = Distance / Speed
- Time = 200 / 17.881
- Time ≈ 11.18 seconds
Answer:
The train will take approximately 11.18 seconds to cross the man standing near the railway line.
Note:
- The options provided in the question are a) 12, b) 15, c) 16, d) 18.
