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