Google Maps reports that, by car, this trip is 772 kilometers, and would take 10 hours 13 minutes. This assumes constant driving at the posted speed limits.
It is a long way to go, however, and you may find yourself stopping occasionally to rest, eat, and so forth, so you should give yourself at least 12 hours, maybe more. It depends on how many stops you intend to take, or if you're on a deadline, etc.
