Worksheet on rates and unit rates, explaining that a rate compares quantities with different units while a unit rate has a denominator of 1. Students practice finding unit rates by dividing the top quantity by the bottom quantity, using real-world contexts such as money per sandwich, miles per hour, dollars per pound, problems per minute, pages per day, and calories per serving. Includes directions plus an answer key with completed calculations, including a rocket challenge with speed in km per minute and distance for 60 minutes.

Answer Key

Name: ______________________________________ Rates and Unit Rates ( B) Remember: A rate compares two quantities with different units. A unit rate has a denominator of 1. To find the unit rate: divide the top number by the bottom number. Example: 180 miles ÷ 3 hours = 60 miles per hour. Directions: Find the unit rate for each problem. Show your division. 1.) $20 for 5 sandwiches Unit rate: $ per sandwich 2.) 240 miles in 4 hours Unit rate: miles per hour 3.) $8.40 for 6 pounds Unit rate: $ per pound 4.) 35 problems in 7 minutes Unit rate: problems per minute 5.) $54 for 9 shirts Unit rate: $ per shirt 6.) 120 heartbeats in 2 minutes Unit rate: beats per minute 7.) $3.60 for 4 pounds Unit rate: $ per pound 8.) 60 pages in 5 days Unit rate: pages per day 9.) $17.50 for 5 gallons Unit rate: $ per gallon 10.) 75 sit-ups in 3 minutes Unit rate: sit-ups per minute 11.) $5.25 for 3 bottles Unit rate: $ per bottle 12.) 315 miles in 5 hours Unit rate: miles per hour 13.) $11.20 for 8 oz Unit rate: $ per oz 14.) 180 calories in 3 servings Unit rate: calories per serving 15.) Challenge Problem: A rocket traveling through space covers 1,560 km in 3 minutes. a) What is the rocket’s unit rate of speed in km per minute? b) At this rate, how far will the rocket travel in one hour (60 minutes)?

Challenge: a) 1,560 ÷ 3 = 520 km per minute b) 520 × 60 = 31,200 km in one hour Mashup Math LLC | Al[l Rights Reserved | Get More K-12 Math Worksheets at www.mashupmath.com](l Rights Reserved | Get More K-12 Math Worksheets at www.mashupmath.com)

FAQs

What is the difference between a rate and a unit rate?

A rate compares two quantities with different units. A unit rate is a rate with a denominator of 1.

How do you find a unit rate?

Divide the top number by the bottom number to get the unit rate.

What does the challenge problem ask you to calculate?

It asks for the rocket’s unit rate of speed in km per minute, then the distance it travels in one hour (60 minutes).
