flying against the wind,an airplanes travels 3850kn in 5 hours. flying with the wind,same plane travels 3510km in 3 hours.what is the rate of the plane in still air and what is the rate of wind
--------------
Equation:
p - w = 3850/5
p + w = 3510/3
----------------------
p - w = 770
p + w = 1170
----
Add and solve for "p":
2p = 1940
plane speed in still air = 970 kmh
-------------------------------
Solve for "w":
p - w = 770
wind speed = 200 kmh
