Have you ever heard someone say, “A car can travel 30 miles per gallon of gas” or “I read 50 pages in 2 hours”? These statements are examples of unit rates. A unit rate is a rate where the second quantity is one unit, like “per gallon” or “per hour.”

Our unit rate word problem worksheets are a collection of problems that ask you to find these rates. They challenge you to apply your mathematical knowledge to figure out how much of something occurs for a single unit of another thing.

Understanding the process required by these essential tools to understand and compare different rates and make informed decisions in various life situations. These problems allow students to relate math to their daily activities, reinforcing the idea that math isn’t just a school subject – it’s a life skill. By practicing and mastering these problems, you’ll be more equipped to navigate the real world, be it shopping, traveling, or any of the myriad situations where unit rates come into play. So, the next time you’re at the store or planning a trip, remember your unit rates, and you’ll be a math champ in no time!

### Examples of Unit Rate Word Problems

Example 1 – Speed

Jake traveled 150 miles in 3 hours. How fast was he going on average?

Solution

Unit Rate = Total Distance / Total Time

Average Speed = 150 miles / 3 hours = 50 miles per hour.

So, Jake traveled at an average speed of 50 mph.

Example 2 – Cost per Item

Lisa bought 4 notebooks for \$12. How much does one notebook cost?

Solution

Unit Rate = Total Cost / Number of Items

Cost per Notebook = \$12 / 4 = \$3.

Thus, each notebook costs \$3.

Example 3 – Earnings

Carlos works at a cafe and earns \$96 in 6 hours. How much does he earn per hour?

Solution

Unit Rate = Total Earnings / Number of Hours

Earnings per Hour = \$96 / 6 = \$16.

Carlos earns \$16 per hour.
