To convert miles to feet, you can use the conversion factor that 1 mile is equal to 5280 feet. Therefore, the appropriate ratio to multiply by is:
5280 feet / 1 mile
When converting 1.7 miles to feet, you would perform the calculation as follows:
\[ 1.7 \text{ miles} \times 5280 \text{ feet/mile} \]
This will give you the distance in feet.
