A pilot can travel 540 miles with the wind in the same amount of time as 380 miles against the wind. Find the speed of the wind

stepladder [879]

T=d/v

540/(230+w)=380/(230-w)

540(230-w)=380(230+w)

124200-540w=87400+380w

124200-920w=87400

-920w=-36800

w=40

So the wind speed is 40 miles per hour.
