The distance from the earth to the moon varies. Call it 700,000 kilometers round trip at 300,000 kilometers per second.

I will not give you the answer, but you may recall v=d/t --> rearrange for t. (t=d/v) d is the distance between the Earth and moon (convert to meters) and v is the speed of light (c) 3.00E8 m/s.
