Approximately how many days does it take the Moon to revolve around Earth?

A.
27.3

B.
29.5

C.
30.1

D.
35.6

A. 27.3

The correct answer is A. 27.3

To find the answer to this question, we need to know the period of the Moon's revolution around the Earth. This can be calculated by dividing the total number of degrees in a circle (360 degrees) by the average daily motion of the Moon, which is 13.2 degrees per day.

Therefore, the period can be calculated as follows:

Period = 360 degrees / 13.2 degrees per day

Approximately, Period = 27.27 days.

So, the closest answer choice is A. 27.3 days.
