in still air. How do you arrive at the conclusion?
First define - what do you need to find?
We need to find - the speed of plane in still air.
Call that a variable.
Let the speed of plane in still air = P
Let the speed of wind = W
Now set up your equations from the given conditions - and continue....
Please share your work with us, indicating exactly where you are stuck - so that we may know where to begin to help you.
