It is a speed.
Time and space are related by the speed of light space r=ct where t is time and c is the speed of light.
Neither light nor time normally has any influence on speed.
Light always travels at the speed of light. The only time that's 299,792,458 meters per second is when the light is in vacuum.
No.
By definition, light travels at the speed of light. About 300,000 kps
Because visible light is emitted at a known frequency (a time) and then it is as simple as Speed = Distance / Time therefore Distance = Speed x Time.
Light always travels at the speed of light. The only time that's 299,792,458 meters per second ( " c " ) is when it's traveling in vacuum.
time dilates, space contracts, speed of light holds constant.
If you observe a clock moving past you at the speed of light, it will appear to you to have stopped.
Time required to do what? To move from one place to another, divide the distance by the speed of light.
Light always travels at the speed of light, although that's a different number in different substances.
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time
