Answer:
17m/s
Explanation:
Given parameters:
Speed of the bird = 12.5m/s
Speed of the wind = 4.5m/s
Unknown:
Speed of the bird when it flies with the wind = ?
Solution:
The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.
Speed of the bird with wind = 12.5m/s + 4.5m/s = 17m/s
It depends on the weight of the sediments.
