Depends.
If I go into Chicago, 52 miles, 90+ minutes, most of that being train (which almost never runs according to the schedule).
If I go to a remote office, 15 miles, and maybe 25 minutes.
Worst ever was a 49 mile commute that was all driving and took about an hour, but only because I worked an off-shift and was driving at the end of rush-hour. Between that driving and house-hunting on the weekends, I was changing the oil every month.
