Question 370143: An airplane took 3hrs to fly 1800 miles against a headwind. The return trip with the wind took 2 hours. Find the speed of the plane in still air and the speed of the wind. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The "speed in still air" is the airspeed.
It's the average of the 2 groundspeeds.
The windspeed is the difference between the airspeed and the groundspeed.
