Started off with the word problem. A plane flies 400 miles with the wind and 300 miles against the wind in the same length of time. If the speed of the wind is 24 mph, what is the speed of the plane in still air?
T = Time X=Speed
Must use system of equations.
T(X+24)=400 - with the wind equation
T(X-24)=300 - against the wind equation
