New York State Common Core Math Module 1, Grade 6, Lesson 16
Lesson 16 Student Outcomes
• Students recognize that they can associate a ratio of two quantities, such as the ratio of miles per hour is 5:2,
to another quantity called the rate.
• Given a ratio, students precisely identify the associated rate. They identify the unit rate and the rate unit.
Lesson 16 Summary
• A ratio of two quantities, such as 5 miles per 2 hours, can be written as another quantity called a rate.
• The numerical part of the rate is called the unit rate and is simply the value of the ratio, in this case 2:5. This means
that in 1 hour, the car travels 2. 5 miles. The unit for the rate is miles/hour, read “miles per hour”.

2. Four football fans took turns driving the distance from New York to Oklahoma to see a big game. Each driver set the
cruise control during his leg of the trip, enabling him to travel at a constant speed. The men changed drivers each
time they stopped for gas and recorded their driving times and distances in the table below.
Use the given data to answer the following questions.
a. What two quantities are being compared?
b. What is the ratio of the two quantities for Andre’s car? What is the associated rate?
c. Answer the same two questions in part (b) for the other three drivers.
d. For each driver, circle the unit rate and put a box around the rate unit.
3. A publishing company is looking for new employees to type novels that will soon be published. The publishing
