The best I managed on my 11.8 mile commute (24 traffic lights only one of which was a right turn and 10 stop signs) was 42:19 or 16.7 MPH.
2:36 stopped, 5:12 at zero power decelerating for lights, time accelerating, and a pannier which makes for a 20% drag increase and ~2 MPH loss on flat ground did not help in spite of riding painfully hard to compensate.
