It is 300,000 kms per Second.
It's officially 299,792.458 km/sec. But it's easier to remember "three hundred thousand",
and that's only 0.07% high, which is usually close enough for the purpose.
The information about a light-year is not relevant to answer this particular question. To find out how far light goes (in a vacuum) in any specific time, simply multiply 300,000 (km/second) by the number of seconds.
Very Far 149296229 meters inside a vacuum such as space or 92768.375 miles
Light travels approximately 0.3 millimeters in one trillionth of a second.
Light travels at a speed of approximately 186,282 miles per second. Therefore, in two seconds, light would travel around 372,564 miles.
It is the distance travelled by light in one year at a speed of 186,000 miles per second

As far as light can travel
Speed doesn't travel. Light travels.Light goes about 300,000 km in a second; in an hour, it goes 3600 times as far, since an hour has 3600 seconds.
Light would travel just less than 1 foot in a billionth of a second, or roughly 11 3/4 inches.
Light travels approximately 186,282 miles (299,792 kilometers) in one second.
Light travels at a speed of approximately 186,282 miles per second. Therefore, in two seconds, light would travel around 372,564 miles.

How far does light travel in one hour
0.3 cm a) one trillionth of a second= 1.0x10^-12 b) light travels at = 3x10^8 meters per second b/a= 0.0003 meters = 0.3 cm actually 0.03cm or 0.3mm or 300µm
