Transcript text: As part of an annual fundraiser to help raise money for cancer research, Heather joined a walkathon. The track she walked on was 1600 yd long. Heather walked 16.5 laps. Her sponsors agreed to donate an amount of money for each mile she walked. How many miles did she walk?
First fill in the blanks on the left side of the equation using three of the ratios shown. Then write your answer on the right side of the equation.
\[
\begin{array}{l}
\text { Ratios: } \frac{1600 \mathrm{yd}}{1 \text { lap }} \quad \frac{1 \mathrm{lap}}{1600 \mathrm{yd}} \quad \frac{5280 \mathrm{ft}}{1 \mathrm{mi}} \quad \frac{1 \mathrm{mi}}{5280 \mathrm{ft}} \quad \frac{3 \mathrm{ft}}{1 \mathrm{yd}} \quad \frac{1 \mathrm{yd}}{3 \mathrm{ft}} \\
\frac{16.5 \text { laps }}{1} \times \square \times \square=\square \mathrm{m} \times \square=\square \square \square \square \square
\end{array}
\]
