What is the average velocity of the moon when it travels twice around the Earth in 24 hours?

A: The distance the moon travels around the Earth divided by the time it takes.

B: It changes as it reaches different points of the motion

C: You can’t tell without a measuring instrument

D: It is 0 m/s

Correct answer: D. The average velocity is calculated as the displacement over time. This is why A is incorrect. The displacement around the Earth in two complete revolutions is 0, thus 0/24 hours will result in an average velocity of 0.
