I would use v=d/t right? but how exactly does the averaging work? Would I find v for each coordinate, then average it with the specified other in brackets, and then average those? Or would I average the coordinates within the brackets, then find v for the "new" coordinate, then average the brackets together? Am I reading too far into this?
