When a plane flies with the wind, it can travel 2160 in 3 hours, When the plane flies against the wind it takes 4 hours to fly the same distance. Find the speed of the plane in still air and the speed of the wind.
--------------
The plane's airspeed is the average of the 2 groundspeeds.
The windspeed is the difference betweeen airspeed and groundspeed.
