SUMMARY
The discussion focuses on calculating the distance from Earth to the Moon using the time it takes for a laser beam to travel to the Moon and back. The time recorded is 2.52 seconds, and the formula used is D=rt, where "r" represents the speed of light, approximately 299,792 kilometers per second. The distance calculation must account for the round trip of the laser beam, effectively doubling the distance from the astronomers to the Moon. The final distance can be determined by substituting the known values into the equation.
