Explanation:
Suppose,the speed of the hawk in still air is
So,while going against wind flow its net velocity becomes
So,if in this process it goes for a distance of
Again when it goes in the direction of wind,its net velocity becomes
Hence, here time required
Now,given that
Solving it we get,
Let the speed of the hawk in still air be
Hence time taken by the hawk to cover a distance of 24 km flying against the wind will be
By the problem
Again in return journey the time taken by the hawk to cover same distance flying with the wind is given by
Adding (1) and (2) we get
