1. Velocity is by definition relative because displacement is by definition relative.

$\displaystyle{ \begin{aligned} v &= \frac{s}{\Delta t} \\ s &= x_2 - x_1 \\ \end{aligned} }$

2. Even for either coordinate ( $x_1$ or $x_2$ ), its value is relative because it is defined with respect to an origin chosen by you.

3.1 Furthermore, even for the origin itself, it is relative in a sense. When you choose a point as the origin of the coordinate system, you have to choose a static point. However, “whether a point is static or not” is subjective for different observers.

3.2 In other words, to be an origin, it has to be the same physical location. However, whether the physical location is the “same” could be up to debate.
