You can put this solution on YOUR website! A cross-country flight traveling with the wind covers 3000 miles in 5 hours. The same plane then changes direction and travels to Texas, against the wind, covering 1500 miles in 3 hours. What are the wind speed, and the speed of the plane in still air?
------------------------
3000/5 = 600 mph downwind
1500/3 = 500 mph upwind
The average is the airspeed, = 550 mph.
The windspeed is the difference, 50 mph.
---------------------
PS Airplanes use knots, not mph. 1 knot = 1 nautical mile per hour.
"speed in still air" is airspeed.
