The key idea here is that
speed of plane in wind = (speed of plane in air) + (speed of wind)
Let be the speed of the plane in still air, and the wind speed. A tailwind blows in the same direction as the plane, so for the first leg of the trip, we have
For the return trip, the wind would blow in the opposite direction:
Solve this system and you'll find and .
The rate of change is the slope so it would be
rise/run
