I don't think that you can. Some things can happen simultaneously and others may be happening during the entire round. 30ft move could be a cautious advance over all 6 seconds, or it could be a short dash over just a few for example.If you had to break a 6 sec combat round down how would you do it? So many seconds for action, movement, etc.
The question came up because of someone falling 120ft and whether or not that person could cast a 1 action spell before hitting.

Sounds like a Dex check.
