What is a unit price?

Back

A unit price is the cost of a single unit of a product, allowing for easy comparison between different products.

How do you calculate the unit price?

Back

To calculate the unit price, divide the total price by the number of units. For example, if 3 candy bars cost $8.21, the unit price is $8.21 ÷ 3 = $2.73.

A unit rate is a comparison of two different quantities where one of the quantities is equal to one unit. For example, speed is a unit rate expressed as distance per time.

Front

How do you find the unit rate of speed?

Back

To find the unit rate of speed, divide the distance traveled by the time taken. For example, if a cheetah runs 60 feet in 4 seconds, the unit rate is 60 ÷ 4 = 15 feet per second.
