Post by: bob werle on May 23, 2009, 11:32:41 PM

No need for a web site.

35' lines, 12 laps per half-mile.
42'; 10 laps,
52.5'; 8 laps,
60'; 7 laps,
70'; 6 laps.

Divide the half mile time into 1800 and you have MPH.
For a full mile, use 3600.

------------

30' is half of 60', so a half mile equals 14 laps.

Thanks but the site would let you inout any line length and # of laps.  I am going to have to figure out mph fo a 14 lap race on 30' lines.

30' is half of 60' so thats a 1/2 mile in 14 laps.  It's an inverse ratio of line length, 60/30 = 2/1.  i.e. halve the length, double the no. of laps required.

What Don said.

Use the 60'/7laps numbers.
