3E8 m/s = 3x(10^8) m/s = 300000000 m/s = Three Hundred Million meters per second
Several thousand years.
The speed of light is 300,000 kilometers per second. If you multiply that by 60, you have the speed in kilometers per minute.
The speed of light is about 880 thousand timesfaster than the speed of sound.
Yes
around 300 thousand kilometers per second in vacuum or air
Light travels through space at a speed of three hundred thousand kilometers per second, which is approximately 186,000 miles per second. This speed is constant in a vacuum and is the fastest speed possible in the universe according to the theory of relativity.

The refractive index of diamond is about 2.42 . So the speed of light in it is (speed of light in vacuum) divided by (2.42) That's 123.9 thousand kilometers per second (about 77,000 miles per second).
500 light seconds = 149,896,229 kilometers
Light goes about 300,000 kilometers in one second. (in a vacuum)
Light travels at 299,792.211 km per second in a vacuum.
If there is an unobstructed path, it can continue traveling practically forever.
