Answer:
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 .
Since the total flying time in both directions was 4.5 hr, so we will equate sum of both times with 4.5 as:
Make a common denominator:
Therefore, the one-way distance was 1200 miles.
