Unit Rates Word Problems Worksheets

What is a Unit Rate? A rate is a comparison or ratio that defines how many of one you have compared to another. Unit rates are just a little more specific. A unit rate distinguishes the quantity of the first type of item compared to a single unit of the second type of item. Students often across this in cars. The speedometer tells unit rate of speed of the vehicle. In the Imperial measurement system, it tells you how many miles the car will travel in one hour. In the metric system it tells you how many kilometers the car will travel in an hour, if it were to maintain that speed for an hour. Every time you go shopping whether it be online or in a store you can use your knowledge of unit rates to determine the best deal. In this case you look on the pricing shelf a unit price is often displayed this indicates the cost of one unit of the item you are buying. The lowest unit price is the best deal every time.

  • Quiz 3 - Erin is making sweaters. Erin took 8 hours to make a sweater. The sweater was made up of 80 kilograms of wool. How long do you think it will take Erin to make sweaters from 800 kilograms of wool?

What is a Price Unit Rate?

We had studied the unit rate before, where we defined the ratio for comparing different quantities. A price unit tells us the cost per 1 unit of any object. For instance, you want to know the per liter cost of milk from your local milk shop. You learned that the milkman is selling milk at $15 per liter. So, if you want to buy 6 liters of milk, you have to multiply $15 and 6 together, you will get an answer of $90. Now, let us compare other unit prices and learn which is the best bargain. There are two stores on the street near your house, named Store A and Store B. One of them sells sugar at $10 per 3 kg, and the other one sells it at $8 per 2 kg. Now, we need to calculate from which shop you can get sugar at a lowered cost. First, let’s calculate the per-unit cost from Store A, where we divide $10 by 3 kg; then, we get a per kg cost of $3.33. Now, we find out the per kg cost of the sugar from Store B; so, we divide $8 by 2kg; then, we get a per kg cost of $4. Therefore, we can conclude that the sugar at the lowest price is available at Store A. These worksheets and lessons show students how to approach word problems that include unit rates, speed, and/or price.
