Answer:
[tex]\frac{54}{9}\text{ miles per hour}[/tex]
Step-by-step explanation:
Unit rate is the units of first quantity in one unit of second quantity.
Given,
Number of miles walked = [tex]\frac{1}{9}[/tex],
Number of hours = [tex]\frac{1}{54}[/tex]
Thus, the unit rate
[tex]=\frac{\text{Number of miles walked}}{\text{Number of hours}}[/tex]
[tex]=\frac{1/9}{1/54}[/tex]
[tex]=\frac{54}{9}[/tex]
= 6 miles per hour
