With a strong wind behind it, a united airlines jet flies 2400 miles from los angeles to orlando in 4 hours and 45 minutes. the return trip takes 6 hours, as the plane flies into the wind. find the speed of the plane in still air, and find the wind speed to the nearest tenth mile per hour?
----------------
With-wind rate: 2400/(4 3/4) = 2400/(19/4) = 505.263 mph
-------
Against-wind rate: 2400/6 = 400 mph
-------
Equations:
p + w = 505.263
p - w = 400
------
Subtract and solve for "w":
2w = 105.263
---
Wind speed = 52.632 mph
