How long should a Dungeon run take?

[KouenElfrit]

The group I usually do dailies with clear lvl70 dungeons roughly between 13-16 minutes, over geared / over leveled content 10-13minutes. We once cleared brayflox hard in 8 minutes (sync'd).

Anytime when I queue roulette without my group, expert averages around 15-22 minutes.

There are a number of factors that determine the speed of how things are cleared, communication is one of them. Good dps is another and knowledge of the dungeon as well.
