Well, my experience would tell me that at that level of airlock activity it is definitely done, but hydrometer readings is the sure way to tell.
Not that NOT taking hydrometer readings is awful, lots of people still use the 1 week in primary, 2 weeks in secondary method. I've been guilty of that myself when in a hurry.
I would take at least one hydrometer reading just to make sure you don't end up with bottle bombs, but a bubble every minute and a half is VERY LITTLE airlock activity.
However, you haven't mentioned a lot yet. What size is your batch? What temp is it fermenting at?
