You know why we know the speeds of light? Arithmetic.

The speed of light could then be found by dividing the diameter of the Earth's orbit by the time difference. The Dutch scientist Christiaan Huygens, who first did the arithmetic, found a value for the speed of light equivalent to 131,000 miles per second. The correct value is 186,000 miles per second.
