At its average distance from the earth, the moon is 1.28 light seconds away.
approximately 3 seconds.
About 1.3 seconds. The Moon is, roughly, 250,000 miles from the Earth, and light travels at 186,000 miles per second.

It takes about 1.28 seconds for light to travel from the moon to Earth. So if the moon were to travel at the speed of light, it would complete an orbit around the Earth in approximately 1.28 seconds.
It takes about 8 and one third minutes to get to the Moon. From the Moon to the Earth only takes a second or so. Of course the light may reach the Earth first, depending on where the Moon is in its orbit around Earth, but it hardly makes any difference.
The moon is already close to the earth
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
That depends on how fast you're going. Light gets there in under 3 seconds but the Apollo Missions took several days to get to the Moon
