If time is relative, is speed also?

Question

If we measure time by the solar year, would we calculate speed on another planet, like mars maybe, differently based on it’s solar year? Or would we use “Earth speed”?

Answer 1

I think we would use miles or kilometers per hour or second. Speed or velocity is relative based on reference frame, but the measurements you would use are the same.
