The speed of light, in vacuum, is exactly 299,792,458 metres per second or 299,792.458 kilometres per second. The values are exact because this is how a metre is defined.
The relationship between a kilometre and a mile is not exact, so it is not possible to give an exact figure for the speed in miles. It is approximately 186,282 miles per second.
It is the same speed all year. If you meant to ask: "How far does the speed of light go in a year?" The Answer is: about 6 trillion miles. EDIT: Light travels 9.454.254.955.488 kilometers per year which translates to 5.874.601.673.407 miles per year. That's about 9.5 trillion kilometers or about 5.9 trillion miles. This distance is called a light-year.
Exactly 299,792,458 meters per second is.
The speed of light is 2.997925 x 108m/s, so 2.997925 x 105km/s
The speed of light is 300,000 kilometers per second. If you multiply that by 60, you have the speed in kilometers per minute.
Electromagnetic radiation, such as light, travels at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is considered to be the maximum speed limit in the universe.
miles... in kph??? Anyway, the speed of light is 300,000 kilometers/second; you can convert that to whatever unit you want. For example, to convert to kilometers/hour, multiply by 3600.
The speed of light in a vacuum is 186,282.397 miles per second or 670,616,629.2 miles per hour.
300,000 kilometers (186,282 miles) per second.
The speed of light in a vacuum is 300.000 kilometers per second, that's 671.000.000 miles per hour.
The speed of light is 1,079,252,848.8 kilometers per hour.
The speed of light is 186,000 miles per second (approximately 300,000 kilometers a second).
It is the same speed all year. If you meant to ask: "How far does the speed of light go in a year?" The Answer is: about 6 trillion miles.

This distance is called a light-year.
In a vacuum, the speed of light is always 670,616,629 miles per hour (300,000 kilometers per second). The speed of light changes as it enters a different medium, such as Earth's atmosphere, but the change in speed is essentially negligible.
the speed of light is 186,000 miles a second it takes the light from the sun takes 7 minuates and 59 seconds to reach earth if the sun explodes it wont be known until the light reaches the earth.
Not only is the question constructed meaninglessly, but it includes a completely false statement of 'fact'. The speed of light is not 300.000 miles an hour. It's more like 300,000 kilometers per second.
The speed of the light is 3.10^8 miles per second.what is the speed in miles per hour
The Speed of Light is 186,000 miles per second.
