Re: No Calibration Needed!
Here's another way to do it.
Keep a constant speed between mile markers. Measure the time in seconds. divide this number into 3600 and the result will be your average speed between those two mile markers.
i.e. 3600/60 sec.=60 mph
3600/65 sec.= 55.38 mph
3600/55 sec.=65.45 mph
