On the outbound you should be fine. You'll land almost certainly in T7 and to get from one end (RCC/Gate 70A) to the other (75-77 area) shouldn't take more than 5 minutes as a casual/slow walker.

I'll let someone else better versed with DEN comment on that. Hopefully your flights are near each other because the walk from one end of the terminal to the other, especially the commuter flight wing, is painfully long IMO.
