Unit Price, Constant Speed, and Unit Rate

What is a unit price?

Back

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

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 4 sweaters cost $96, the unit price is $96 ÷ 4 = $24 per sweater.

What is a constant speed?

Back

Constant speed means moving at a steady rate without speeding up or slowing down. For example, driving at 60 miles per hour consistently.

How do you find the unit rate?

The unit rate is found by dividing two quantities to find out how much of one quantity corresponds to one unit of another. For example, if a car travels 300 miles in 5 hours, the unit rate is 300 miles ÷ 5 hours = 60 miles per hour.
