When I'm commuting, I think of it in terms of efficiency as well. I work out nearly daily, and when I commute, I can get a 1hr 10 min workout in (that's round trip) at the cost of 40 minutes (it would take me 30 minutes RT to drive).
Actually, you also need to account for the time you'd be working out if you weren't commuting on your bike. I'd bet it would be more than 40 minutes, so you are actually ahead!
