Question 553313
A plane left an airport and flew with the wind for 4 hours, covering 2000 miles. It then returned over the same route to the airport against the same wind in 5 hours. Find the rate of the plane in still air and the speed of the wind.
--------------
2000/4 = 500 mi/hr
2000/5 = 400 mi/hr
----
The plane's airspeed is the average, 450 mi/hr
The windspeed is the difference, = 50 mi/hr
