> Speed is is the magnitude of velocity so bigger is faster. If you're going to be pedantic, velocity is a vector, and vectors must reside in a vector space, so what vector space do the velocities in this context reside in? Ignoring all context to call into doubt the use of a perfectly well-understood word adds nothing to the discussion.
