if i get on a subway train at the very back, then wait for it to start moving, then run up the middle to the front, i'm passing the people who are sitting. the trip average seated speed is the same as the trip average train speed, but if i'm going a little faster than them for a little bit, my overall average speed is a little faster.
so didn't i get there before they did?
OF COURSE I DID!

GOT THE DROP ON ALL YOU MOTHER FUCKERS

CAN'T SEE SHIT, CAPTAIN

i bumped into all of them along the way, in probably awkward ways! i win any way you look at it!

Actually, you'd also have to account for the motion of both on the planet, and the planet, relative to the local frame as well.
