**A unit rate in math is the expression of a rate in a quantity of one.** For example, 60 miles per hour represents a commonly used unit rate. Similarly, 30 students per school bus also represents a unit rate.

Unit rates actually are utilized by people frequently in every day life. A standard work week undertaken by a typical person is 40 hours per week. Unit prices are useful at grocery stores. For example, if five potatoes cost $5, the unit price is determined by dividing the total price by the number of individual potatoes, or $5 divided by 5.
