Understanding the Scenario
To solve the problem, we need to determine the time taken by the bird flying south to cross the length of the train moving north.
Key Parameters
- Length of the train: 180 meters
- Speed of the train: 25 m/s (north)
- Speed of the bird: 5 m/s (south)
Relative Speed Calculation
Since the train and the bird are moving in opposite directions, we can calculate their relative speed:
- Relative speed = Speed of the train + Speed of the bird
- Relative speed = 25 m/s + 5 m/s
- Relative speed = 30 m/s
Time to Cross the Train
To find the time taken for the bird to cross the entire length of the train, we can use the formula:
- Time = Distance / Speed
- Distance = Length of the train = 180 meters
- Speed = Relative Speed = 30 m/s
Now, substituting the values:
- Time = 180 meters / 30 m/s
- Time = 6 seconds
Conclusion
The bird takes 6 seconds to cross the train. This calculation considers the combined speeds of both the bird and the train, providing a clear understanding of the time taken for the crossing.
