We consider two most popular definitions of velocities of remote objects inGeneral Relativity. Our work has two motivations. From a research point ofview, we generalize the formula connecting these two velocities in FRW metricsfound by Chodorowski to arbitrary synchronous spherically symmetric metrics.From a methodological point of view, our goal is to outline certaincounter-intuitive properties of the definitions in question, which would allowto use them when it is reasonable and to avoid incorrect statements, based oninappropriate use of intuition.
