70 MPH for 25 minutes equals 29.1 Miles. Now, my Crusie Control ain't the best so I could be going 72-73 MPH, but I DON'T speed (I know the cop I pass every morning on the way to work is parked SOMEWHERE along my commute route). He writes a lot of tickets, so it keeps me honest. Also the 30 miles is what the Department of Transportation CLAIMS is the distance. We can't trust the DoT to fill in a pot hole, let alone do basic math.
So I'll rephrase myself.
I drive what the DoT claims is 30 miles at what my cruise control claims is 70 MPH.
I mean it about the cop. I have yet to go to work without seeing him along the side of the road pointing his little radar gun at everyone who passes. Really annoying. (More so for those unaware of his presence so he can nail them going 80 to try to get to work on time).
