Answer:
[tex]3 mi/hr[/tex]
Step-by-step explanation:
The rate of miles per hour refers to the speed, which is calculated with:
[tex]s=\frac{d}{t}[/tex]
Where:
[tex]d=\frac{2}{3}mi[/tex]
[tex]t=\frac{2}{9}hour[/tex]
Replacing all values, we have:
[tex]s=\frac{\frac{2}{3}mi}{\frac{2}{9}hour}=\frac{18}{6} mi/hour\\s=3 mi/hr[/tex]
Therefore, the ratio is
[tex]3 mi/hr[/tex]
