Just as I figured. A non response.
Anyway, speed of light is a convention, agreed upon by international standards.
Why? Because you can’t use two clocks, due to issues with physics and relativity. Can’t use one clock because then it is an average. An average of two legs means neither one leg can be known, but they add up to a cumulative elapsed duration.
So, being unable to determine a one way leg, the duration of either individual leg is impossible to know, except by averaging.
0+8/2=4, 3+5/2=4, 6+2/2=4 solution is 4.
Replace any speed of light system, radar, for example, with any solution for a two way duration and it works.
But, anyway.

“Anyway, speed of light is a convention, agreed upon by international standards.”
ROTFLMAO!
A second is convention based on the measured speed of light.
A meter is convention based on the measured speed of light.
