Distance = (speed) x (time)
(Speed of light) x (697 years) = (60,000 km/hour) x (time)
Time = (speed of light) x (697 years) / (60,000 km/hour)
Time = (300,000 km/sec) x (1 hour/60,000 km) x (3,600 sec/hour) x (697 years) = 12,546,000 years

1 light year = 9.4605284 × 1015 meters
A light-year is about 9.46 x 1015 meters.
48.6 degrees
It doesn't have a velocity! However, in theory, one could say that darkness is the only thing that replaces light!! So as light goes away, darkness takes its place!! So darkness probably travels at the speed of light :D - 186000 miles per second (that's about 7.5 times round the earth in a second)
the velocity of light is 300000000 m/s
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
No, velocity and color are independent. Color is determined by frequency, and speed is determined by what material the light is traveling through.
Light travels at a constant speed of approximately 299,792 kilometers per second in a vacuum. This speed is often referred to as the "speed of light." Velocity, on the other hand, is a vector quantity that includes both speed and direction, so the velocity of light would depend on the direction in which the light is traveling.

As long as they're all traveling through the same material, all colors of visible light have virtually identical speed.
c is a constant variable commonly known as "the speed of light", but more correctly the velocity of the speed of light ought to be called "the velocity of the speed of electromagnetic wave interactions". And it is precisely 299,792,458 meters per second.
The neutrino was recently discovered to have a velocity greater than that of light in a vacuum. This discovery was made in experiments such as OPERA where neutrinos were observed traveling faster than the speed of light, although those results were later retracted.
The velocity of light in a material is given by the speed of light in a vacuum divided by the refractive index of the material. In this case, the velocity of light in alcohol with a refractive index of 1.36 would be about 220,000 km/s.
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.
c = f x ^ (velocity)
300,000,000 meters per second.(or 300,000 kilometers, or 186,282 miles, or 1,490,256 furlongs)
