an airplane travels 3835 km against wind in 5 hours and 4785 km with the wind in the same amount of time. what is the rate of the plane in still air and what is what is the rate of the wind?
-------------
Find the 2 groundspeeds, upwind and downwind.
d = r*t
r = d/t
------------
The plane's airspeed is the average of the 2.
----
Windspeed = difference between groundspeed and airspeed.
