For me, the minimum walking distance to classes is seven minutes...but then again, I'm out walking for at least half an hour a day, plus getting lost (add on another half to whole hour, maybe? More if I'm seriously lost), and then activities and such (tack on another three hours of standing). And then I'm on the second floor, but I live on The Hill, so...more steps! And CMU is built over a ravine, so depending on where you're going, there might be a lot of uphill/downhill.
