Question

To covert a distance of 1.7 miles to feet, which ratio could multiply by?

5280 ft/1mile
12inches/1foot
1foot/5280miles
1miles/5280ft

Answer 1

To convert a distance of 1.7 miles to feet, you need to use the ratio that directly relates miles to feet. The ratio you should use is:

\[
\frac{5280 \text{ ft}}{1 \text{ mile}}
\]

So, you would multiply 1.7 miles by this ratio:

\[
1.7 \text{ miles} \times \frac{5280 \text{ ft}}{1 \text{ mile}} = 8,976 \text{ feet}
\]

Thus, the correct ratio to multiply by is \( \frac{5280 \text{ ft}}{1 \text{ mile}} \).
