Problem
QUESTION 2 10 points Save Answer Use a proportion to solve the problem. On a map of the Fox River, 1 centimeter represents 3 kilometers. If a trail by the river is actually 14.70 kilometers long, what is the length of the trail on the map? \( 6.7 \mathrm{~cm} \) \( 11.7 \mathrm{~cm} \) \( 6.9 \mathrm{~cm} \) \( 4.9 \mathrm{~cm} \)
Solution
Step 1 ：\(\frac{1\mathrm{~cm}}{3\mathrm{~km}} = \frac{x}{14.70\mathrm{~km}}\)
Step 2 ：\(x = \frac{14.70\mathrm{~km}}{3\mathrm{~km}}\mathrm{~cm}\)
Step 3 ：\(x\approx4.9\mathrm{~cm}\)
