How long does it take for the moon to complete one revolution around Earth?

Answer

C
365 days
D
27.3 days

Explanation

The Moon takes about 27.3 days to complete one orbit, or revolution, around Earth. This is different from the roughly 29.5 days between repeating phases, because Earth also moves around the Sun during that time. So the correct choice is 27.3 days.
