Unit Rate on Shmoop: http://www.shmoop.com/ratios-percentages/unit-rate.html
Approximately 874 people per day wonder what a unit rate is. A unit rate is an expression of two subjects that are measured in different units, such as people and days, and then reduced to a single unit for one of those subjects. We just made up that 874 number, but it's no surprise, since we make up 22 numbers per minute here at Shmoop.
