Answer:
The speed of the wind is 25 km/hr.
Explanation:
Let us call
the speed of the plane and
the speed of the wind. When the plane is flying against the wind, it covers the distance of 900-km in 2 hours (120 minutes); therefore;
(1). 
And when the plane is flying with the wind, it covers the same distance in 1 hour 48 minutes (108 minutes)
(2). 
From equation (1) we solve for
and get:
,
and by putting this into equation (2) we get:





or in km/hr this is

Answer:
The value is
