Since I live in the countryside, the lack of traffic, and fairly even roads give me an average of about 28 KPH/, but it depends greatly on the day, my condition. Sometimes I go slower, sometimes faster, and sometimes I just feel like enjoying the view and going a bit slower. Having a really hot day also makes the cycling a bit slower, and I also have the tendency to day dream, which makes me as slow as a snail. When I am in the city I don't even bother recording my speed, since traffic and other things prevents me from actually going in an even pace.
