In a vacuum, the speed of light is always 670,616,629 miles per hour (300,000 kilometers per second). The speed of light changes as it enters a different medium, such as Earth's atmosphere, but the change in speed is essentially negligible.
About 186,000 miles per hour or 300,000 kilometers per hour.
How far does light travel in one hour
Light travels at 670,616,629 miles per hour from the sun to Earth (or anyplace else in a vacuum). It takes about 8 minutes 12 seconds for the light of the sun to reach Earth.

186'000 miles an hour or speed of light
Light takes about 8 minutes to travel from Earth to the sun. The sun is about 93 million miles away, so it would take about 177 years to get to the sun in a car traveling at 60 miles per hour, and about 21.5 years to get to the sun in an airplane traveling at 500 miles per hour. (These are just comparisons; cars and airplanes don't travel in outer space.)
Light travels at about 670 million miles per hour.

Radio waves travel at the speed of light which, in a vacuum, is about 3 x 108 meters per second.
By definition, light travels 299,792,458 meters per second. This gives 299,792.458 kilometers per second. Multiplying by 60 gives 17,987,547.48 kilometers per minute, and multiplying again by 60 gives the distance traveled per hour. It is 1,079,252,848.8 km/h. See the related link for more information.
Microwaves travel at the speed of light, which is about 299,792 kilometers per second in a vacuum.
