Question 1153778
An airplane can fly 650 mph in still air. If it can travel 2800 miles with the wind in the same time it can travel 2400 miles against the wind, find the wind speed.
--------------
a = plane's airspeed = 650
w = windspeed
----
t = 2800/(650+w) = 2400/(650-w)
2800*(650-w) = 2400*(650+w)
7*(650-w) = 6*(650+w)
4550 - 7w = 3900 + 6w
13w = 650
w = 50
