37.5% of 96 is 36.

This is correct.
Big Dutch: It is a straight up ratio of one number related to another.
The fact that you are calculating vehicle speeds is immaterial. The math would be the same if it was a compression ratio, a cookie recipe or comparing your net earnings to your gross earnings.
The link geezer provided is the one I always use.
