Provide an appropriate response.Suppose that Jody drove 80 miles in 2 hours. Dividing 80 by 2 tells us how many miles Jody drove in each hour. The units for this rate are miles per hour (mi/hr). If we divide 2 by 80 what information would this give us? Give an interpretation of the rate  = 0.025. What units would be used for this rate?

What will be an ideal response?


Answers will vary. The rate  = 0.025 tells us how many hours it took Jody to drive each mile. The units are hours per mile (hr/mi).
