Time for radio waves to reach moon?

Chatito · Sep 20, 2015

So I was thinking that radio waves travel at the speed of light, approximately 300,000,000 m/s.I was wondering how much time it would take if the average distance from Earth to the Moon is 384,000 km.

Well, how many kilometers are in 300,000,000 meters?

Using speed = distance / time, what do you get? If that doesn't help, where do you get stuck?
