The earth take's 365 and one fourth day's to complete one revolution.

My almanac lists the average distance from earth to moon as 384,401 km. Round trip = 768,802 km. Time = (distance) divided by (speed) = (768,802,000) / (3.8 x 108) = (7.68802 x 108) / (3.8 x 108) = 2.563 seconds (rounded)
Jupiter and Earth are not always the same distance apart. At their closest, it would take about 1.96 seconds. At their furthest, about 3.22 seconds.
It takes approximately 8 minutes and 20 seconds for sunlight to travel from the sun to the Earth at the speed of light.
The Earth is (on average) 93 million miles from the Sun, and light travels at 186,000 miles per second. It's a curious coincidence tha the math on this says that light travels from the Sun to the Earth in a nice, round, 500 seconds. This is equal to 8 minutes 20 seconds.
it takes 5 seconds
About 500 seconds
27 days 7 hours 43 minutes and 11.6 seconds
It would take a radar signal 299.40 seconds to complete a round trip.

27 days, 7 hours, 43 minutes and 11.6 seconds - roughly 28 days :D
It would take a radar signal 3049600 seconds to complete a round-trip between Earth and Mars. Divide by 60 to get minutes and divide again to get hours.

it takes 271/3 days
It take's about eight minutes for sun to reach earth
