If I ride alone, or with my husband, I generally average between 14.5 and 15.5, once in awhile around 16. My riding is mostly in rolling areas, but some rides have significant climbs (between 7-12 %). Generally, I do around 8-10 on moderate hills and around 6, sometimes down to 5 on steep, long climbs. I spin up them, since standing hurts my knees for any significant amount of time. I lose time on the descents; I'm a chicken and my technical skills still suck after 5 years of riding. The fastest I've hit is 32 mph, hope to get it up to 40 this yr. A lot of my rides are with a friend who rides much slower than me, so my overall average is lower because I ride at her pace, or a little faster (12-13). I am also pretty sociable while riding, if I am with someone, so basically I don't focus so much on my speed anymore. I've gone from an average of 11-12 to 14-16, so I'm happy.
