Answer:
It would take 10.25 hours to fly 82000 miles.
Explanation:
Since the distance is proportional to the time, we can create a proportion to find how many hours (t) it would hake to fly 82000 hours:
73680 miles / 9.21 hours = 82000 miles / t hours
73680/9.21 = 82000/t
(8000 = 82000/t) * t
(8000t = 82000) / 8000
t = 10.25
Thus, it would take 10.25 hours to fly 82000 miles.
