Question 664893
With a strong wind behind it, a jet flies 2400 miles from LA to Orlando in 4 3/4 hours. The return trip takes 6 hrs because the plane flies into the wind. If the wind speed is the same on each trip find the speed the plane in the still air and find the wind speed to the nearest tenth of a mile per hour. 
-------------
d = r*t
r = d/t
Use that to find the 2 groundspeeds.
The airspeed of the plane is the average of the 2.
--------
The windspeed is the difference of the airspeed and the groundspeed.
