Answer
This represents the speed of light in a vacuum, which is approximately 300,000,000 meters per second (or 300,000 km/s). In scientific notation, this is written as 3×10⁸ m/s. The letter 'c' is the universal symbol for the speed of light, which is the fastest speed possible in the universe according to Einstein's theory of relativity.
