Love this question! Because we were using quotative division, we are dividing by the rate whereas partitive division, you are dividing by the quota.
Keep in mind, we were contriving a composed unit with the two trucks scenario so it definitely doesn’t “feel” right to be scaling in tandem… so the rate is pretty contrived here, but still technically a quantity per group situation.
Does that help? Feel free to dig deeper on this one…
