Question 307069
A certian plane can travel 1500 miles in 5 hours when flying into the wind.  The same plane can travel 2000 miles in 5 hours when flying with the wind.  Find the rate of the wind.
-----------------------
1500/5 = 300 mph
2000/5 = 400 mph
The plane's airspeed is the average = (300+400)/2 = 350 mph
The wind speed is the difference, = 400-350 = 50 mph
