Calculate 1/4

Best run was 60' at 2.00, 1/8 at 8.5 =79.80

I know these numbers are not that great, but was wondering if this was a quarter mile track what time could be added for an accurate 1/4?

I seem to remember a conversion factor of 1.57.

8.5 x 1.57 = 13.345

Rough guess on the MPH

79.80 + 20 = 99.80

Faster car will pick up closer to 25 MPH on the back half of the 1/4.
