I would have been out of the competition on this one.
-I tried the Make Groups Tool, but then scrapped it and went with the Summarize Tool.
-Great Discussion that you all are having here:
-The instructions said to make groups and not necessarily use the Make Groups Tool, as my experience with it has been that when you don't have the confidence in a tool, it is best to not use it and especially when you are on the clock you just want a working solution. Later, you can always go back and "Clean up," as I have seen this in my role where I had a working workflow early on that was a bit "dirty/sloppy," but worked and was criticized, only to later go back and "clean it up,".
-The "dirty" workflow got us the information we needed for a time limited project...
Nonetheless, a win is a win, so any way that you can reach the finish line is legal in my book.

Took me a while to find the correct spatial tool and use it right, so total time for this one appox. 15 minutes...
It took me some time to figure out how to do the correct rounding of the result, but a quick search in the search bar
