Final answer:
Light takes approximately 1.28 seconds to reach Earth from the Moon.
Step-by-step explanation:
In order to calculate the time it takes for light to reach Earth from the Moon, we need to use the speed of light. The speed of light is approximately 299,792 kilometers per second.
Given that the Moon is 3.84 x 105 km away, we can calculate the time it takes for light to travel that distance.
Using the formula time = distance / speed, we find that the time it takes for light to reach Earth from the Moon is approximately 1.28 seconds.
