how many hours are in Neptune and saturn

Answer 1

15 hours in a day on Saturn.

Explanation:

Let's use "x" to represent the number of hours in a day on Neptune:

- According to the information given, a day on Saturn lasts 0.6875 times as long as a day on Neptune. This means that the number of hours in a day on Saturn is 0.6875x.

- The number of hours in a day on Saturn is 3 more than half the number of hours in a day on Neptune. Using algebra, we can write this as: 0.5x + 3 = 0.6875x.

- Solving for "x", we get x = 24. Therefore, there are 24 hours in a day on Neptune.

- Plugging in x = 24 in the equation 0.5x + 3 = 0.6875x, we get 15 hours. Therefore, there are 15 hours in a day on Saturn.
