It's consistently relative, because the unit of speed we use is relative to our subjective experience. Hell, if you were American you would've given these values in miles/hr, so localised is the subjectivity of distance. Hours too are a relative measure of time (consider an alien who could live for thousands of years and how they would measure time, or a being that could travel near the speed of light).
