10.8 miles, about 20 minutes by car, 40 to 50 minutes by bike. Nearly 100% rural 50 MPH roads with no stops and no traffic. It's a very nice ride, and also a very nice drive, woods and farm fields around the roads, etc, but it also means that in a car you go the whole distance at the speed limit of 50, so it's certainly much slower by bike.
In the summer if I'm not fighting a headwind I can do it in as little as 33 minutes on a bike.
