During an Apollo moon landing, reflecting panels were placed on the moon. This allowed Earth-based astronomers to shoot laser beams at the moon's surface to determine its distance from Earth. The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
