Question 762764: A man flies a small airplane from Fargo to Bismarck, North Dakota—a distance of 180 mi. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 h 15 min. What is his speed in still air, and how fast is the wind blowing?

--------------
Find the 2 groundspeeds.
The airspeed is the average of the 2.
---
windspeed is the difference between airspeed and groundspeed.
