Jill is the leading scorer on her basketball team, with an average of 13.2 points per game. Which BEST describes Jill's scoring average: rate or ratio?

Answer 1

rate

The "per" usually indicates a rate, as in

miles per gallon
population per square mile

Answer 2

on the other hand, rate usually involves a time period, as in

km per hour
ft per second

So, I think I'd have to change my answer to ratio, the ratio of points to games.
