1) Since we have a scale let's find out the distance between them
Given the relationship, since they are proportional let's cross multiply them:
1 inch = 13. 9 miles
3.5 x
2) Writing as ratios:
[tex]\begin{gathered} \frac{1}{3.5}=\frac{13.9}{x} \\ x=13.9\text{ }\times3.5 \\ x=48.65 \end{gathered}[/tex]3) If they are 3.5" according to that proportion, then those two cities are 48.65 miles apart.
