Question

I NEED HELP PLEASE, thanks! :)
A laser beam from Earth is reflected back from a mirror on the Moon in 2.60 s. If the distance between Earth and the Moon is 3.85 × 108m, calculate the speed of light. Please show all work.

Answer 1

Answer:

2.96×10⁸ m/s

Explanation:

Speed = distance / time

v = (2 × 3.85×10⁸ m) / (2.60 s)

v = 2.96×10⁸ m/s
