This task could be used by teachers to help students develop the concept of unit rates. Its purpose is to help students see that when you have a context that can be modeled with a ratio and associated unit rate, there is almost always another ratio with its associated unit rate (the only exception is when one of the quantities is zero), and to encourage students to flexibly choose either unit rate depending on the question at hand.
This task is best suited for use with an instructor or for enrichment with students who have a strong understanding of ratios and rates. There is no explanation for using the given ratio to determine the rates used to answer the questions.
