Question

1. road maps are drawn to scale. using a scale of 1 in. = 10 mi, how many inches should a distance of 185 mi measure with a ruler on this road map?

Explanation:

Let $x$ be the length in inches on the map. We have the proportion $\frac{1}{10}=\frac{x}{185}$.

Step2: Cross - multiply

$10x = 1\times185$.

Step3: Solve for $x$

$x=\frac{185}{10}=18.5$.

Answer:

$18.5$ inches
