a plane traveled 1078miles to Abuja and back. the tip there was with the wind. it took 7 hours. the way back was into the wind. the trip back took 11 hours. find the speed of the plane in still air and the speed of the wind.
-------------
The plane's airspeed is the average of upwind and downwind groundspeeds.
Downwind = 1078/7 mi/hr
Upwind = 1078/11 mi/hr
---------------------
The windspeed is the difference between airspeed and groundspeed.
