I would say I actively engaged in PvP ~10% of my play time. During that time, I would say we got into 1 fight per ~45 minutes. Nullsec gang patrolling with gate bookmarks or gate camping. That's not counting any time spent in larger fleet actions.
And granted, this is ~10 years old vs current features and meta.
So that would add up to... 1:7.5 hours (clock time) or 1:15/22.5 (2x & 3x logged net)?
