3 clocks thought experiment - Absolute vs. relative aspects?

[QUOTE="Nugatory, post: 6899478, member: 382138"] Relative velocity is the first derivative of the position when using coordinates in which the object to which the speed is relative is at rest. It is a vector. Relative speed is the magnitude of the relative velocity and is a scalar. Thinking in terms of "distance" just gets in the way except when working with objects that are at rest relative to one another. Be aware that just about everyone is occasionally careless about the distinction between speed and velocity when it is clear from the context which one is being discussed. [/QUOTE]
