What is a unit rate? A unit rate is a rate expressed in a quantity of one unit. A car traveling at a rate of 60 miles per hour, for example, is an expression of a unit rate. It describes the car's traveling rate over 1 hour of time.
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.ou could also find the unit rate by dividing the first term of the ratio by the second term. When prices are expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, they are called unit prices.
