Mastering Unit Rates and Their Applications

The video tutorial explains the concept of unit rate, which is a comparison of two measurements where one term has a value of one. It provides examples such as dollars per hour and miles per hour. The tutorial includes practical examples: calculating words per minute, determining problems solved per minute by students, and finding the cost per goldfish. Each example involves dividing the total quantity by the number of units to find the unit rate.
