Neptune can complete a rotation at 18 to 20 hours. You're rania's can make one in 16 to 28 hours. What is the average time it takes Neptune to complete rotation? What is the average time it takes uranus to complete a rotation? What is the average for both planets?

To find the average time it takes Neptune to complete a rotation, we can add the minimum and maximum times and divide the sum by 2. Using the given information, the minimum time is 18 hours and the maximum time is 20 hours.

Average time for Neptune = (18 + 20) / 2 = 19 hours.

To find the average time it takes Uranus to complete a rotation, we can follow the same process. The minimum time is 16 hours and the maximum time is 28 hours.

Average time for Uranus = (16 + 28) / 2 = 22 hours.

To find the average for both planets, we can add the average times for Neptune and Uranus, and then divide the sum by 2.

Average time for both planets = (19 + 22) / 2 = 20.5 hours.
