I was noticing the tenths part of my odometer today. I drive rather fast and noticed that the tenths were going from 1 to 2 to 3 etc… every three seconds or so…

I was wondering, how fast would I have to drive for my tenths to move from number to number every second?

In other words, if it were on 328 and 6/10’s of a mile, how fast would I have to drive for it to register 328 and 7/10’s of a mile in one second.

That’s 10 seconds per mile, which is flying. Remember if you are doing 60 MPH you are going
at exactly one mile per minute, or one mile/60 seconds. If you are going one mile/10 seconds,
your speed is 6x as fast, which is 360 MPH, which is Top Fuel dragster territory. I’ll note
that 3 seconds per marker is 30 seconds per mile, or 120 MPH. Hope you have your radar
detecting device in good working order…

Yeah, i drive about 885 when there isn’t too much traffic on the Beltway. So, my initial statement about the tenths moving every 3 seconds was a little off, maybe every 4-5 seconds.
