Answer:
60 miles per hour.
Step-by-step explanation:
Let r represent speed of wind blowing in miles per hour.
We have been given that the cruising speed of the plane was a constant 360 mph in air. The speed of the plane is the direction of wind would be
.
The speed of the plane is the opposite direction of wind would be
.

Distance covered in the direction of wind would be
.
Distance covered in the opposite direction of wind would be
.
Since both distances are same, so we will get:






Therefore, the wind is blowing at a rate of 60 miles per hour.
