Question 458011: It takes a plane eight hours to fly 1280 miles with the wind. If it takes it 12 hours and 48 minutes (12.8 hours) to cover the same distance when flying against the wind, find the speed of the wind in miles per hour. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 1280/8 = 160 mph
1280/12.8 = 100 mph
The plane's airspeed is the average = (160 + 100)/2 = 130 mph
The windspeed is the difference = 160 - 130 = 30 mph
