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
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
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.
Light travels approximately 0.3 millimeters in one trillionth of a 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
A light-year is a measure of distance, just like a foot, a meter or a mile. A measure of distance is not considered to travel. If the question is how far light travels in one second, the answer is 299,792.458 kilometers, or about 186,286 miles. The speeds noted refer to light moving in a vacuum.
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
