let x be the distance from New Orleans to Atlanta
...
speed forward = 320 mph
speed return = 280 mph
...
time forward +time return = 3 hours
x/320 + x/280 = 3
280x+320x / 280*320=3
600x = 3*280*320
x= 3*280*320/600
distance = 448 miles.
speed forward = 320 mph
time = 448/320
= 1.4 hours
OR 1 hour 24 minutes

Flying X miles at 320M/H should be shown as
as the above will give time as a result, i.e
Since the distance is the same, the return trip was
as the above will give time as a result, i.e
and

multiply thru by 2240

X= 448
The distance each way was 448 miles.

Note, the average speed is not 300. Half the distance was spent at 320, half at 280, but not half the time.
