Question 372700: A man flies an airplane from Fargo to Bismark -- a distance of 180 mi. Because he is flying into a head wind, the trip takes 2 hours. On the way back, the wind is blowing the same speed, so it takes an 1 hour and 48 mins. What is his speed in still air and how fast is the wind blowing?

On the way back, the wind is blowing the same speed, so it takes an 1 hour and 48 mins. What is his speed in still air and how fast is the wind blowing?
---------------
Upwind, the groundspeed = 180/2 = 90 mph
Downwind, = 180/1.8 = 100 mph
The "speed in still air" is the airspeed, and it's the average = 95 mph
The windspeed is the difference = 5 mph
