Answer: The unit rate = 3 miles per inch.
Step-by-step explanation:
Given: Distance on map = [tex]5\dfrac12[/tex] inches [tex]=\dfrac{11}{2}[/tex] inches
Actual distance = [tex]16\dfrac12[/tex] miles [tex]=\dfrac{33}{2}[/tex] miles
That means 1 inch on map = [tex]\dfrac{\dfrac{33}{2}}{\dfrac{11}{2}}\ miles[/tex]
[tex]=\dfrac{33}{2}\ miles[/tex]
[tex]=3\ miles[/tex]
Hence, the unit rate = 3 miles per inch.
