Answer

3×10⁸ m/s (or 300,000,000 meters per second) is approximately the speed of light in a vacuum, denoted by 'c'. More precisely, the speed of light is 299,792,458 m/s, often rounded to 3×10⁸ m/s for calculations. This is the fastest speed possible in the universe and is fundamental to Einstein's theory of relativity.
