1200 miles.
Step-by-step explanation:
Let d represent one way distance.
We have been given that a plane averaged 800 mph on a trip going east, but only 400 mph on the return trip.
The time taken while going east would be .
The time taken while returning back would be .

Make a common denominator:
Therefore, the one-way distance was 1200 miles.
