Best Answer

That is approximately the speed of light (c). In metric units it is exactly 299792458 meters per second (299792.458 kilometers per second). Even electrons in atoms travel at approximately the same speed (but always less than speed of light)

The speed of light cannot be measured IN A WAY. However it travels at 1,079,252,848.8 miles per hour or 299,792,458 meters per second. It cannot be measured however the numbers I showed is one way. Light cannot have a specified measurement, unless the light source is big or small etc...


What travels at 380000 kilometres per second?

Nothing. Or at least, nothing that we could ever detect. The problem is, the speed of light is 300,000 km per second, and your speed is 80,000KM/sec faster than that. According to our current understanding of physics, nothing material can travel AT the speed of light.
