Oh, I forgot to point out another interesting thing! In the first part of The Badge and the Burden, when all the students rush to class, we can see them running.

Considering the fact even though Weiss left the dorms exactly 3,15 seconds before Ruby, they end up running almost alongside each other, it seems Ruby catched up to her, thus making her faster when none of them are using their semblances.
