PIZZAQ: my neighbor measures the time it takes for his radar to reach la Lune and return to his backyard
but not more helpful
4 slices with pepperoni, wild mushrooms and shallots:
My amateur radio neighbor aims his radar dish at the Moon. His radar signal bounces off the Moon, and his parabolic dish receives the echo 2.6367241033 seconds later.
At that moment, how far is my neighbor's backyard from the surface of the Moon? Please give your Answer in kilometers.
