How many minutes is required for sunlight to travel from the sun to earth? (assume the sun is 93,000,000 miles from earth and that sunlight travels at 1.86 × 105 miles per

To determine the time it takes for the sunlight to travel from the sun to earth, we need to have information of the speed of the light and the distance from the sun to the earth. If we have these, we can simply divide the distance by the speed to obtain the time. We do as follows:

time = distance / speed
time = 93,000,000 miles / 1.86 × 10^5 miles per second
time = 500 seconds

We have to convert it to minutes since it is asked.

time = 500 seconds ( 1 minute / 60 seconds ) = 8.33 minutes.

Therefore, the time it takes for sunlight to travel from the sun to the earth would be about 8.33 minutes.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
