Roughly 1.28 seconds (rounded)
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 1.3 seconds since the distance between the Earth and the Moon is 230,100 miles and light travels 186,282 miles per second.
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
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 speed of light is 300,000 km per second. The Moon's distance varies between about 360,000 km and 405,000 km from the Earth. So it takes a little over a second for light reflected from the Moon to reach Earth.
The Apollo spacecraft took 3 days to travel from the Earth to the moon.
about a month
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
as long as the earth's been round!
I would imagine the speed of Electricity in a bolt of lightening is very close to that of light ... light travels at 187000 mph...The moon is 238,857 miles from earth. If you divide the speed of light from the distance to the moon, you get about 1.27 hours (1 hour, 16 minutes, and 20 seconds
About 1.3 seconds
The distance from the Moon to Earth is a little more than one light-SECOND, meaning it takes light a little over a second to travel that distance.
