2. During her daily run, Mira looks at her fitness monitor and sees that she has run 9 miles so far. If this distance is 30% of the total distance she plans to run, how many total miles does Mira plan to run?
[tex]let \: total \: distance \: be \: x \\ 30\% \: of \: x = 9 \\ \frac{30}{100} \times x = 9 \\ 30x = 900 \\ x = 30 \\ total \: distance = 30 \: miles[/tex]
