Answer:
171 miles
Step-by-step explanation:
The scale drawing shows a distance of 4 1/2 inches, which is equal to 9*(1/2) inches. Since every 1/2 inch in the drawing represents 19 miles, the actual distance is 9*19, which is 171 miles.
You can also use dimensional analysis to solve this as follows: [tex]4 \frac{1}{2} \text{ in} \cdot \frac{19\text{ miles}}{1/2 \text{ in}} = 171 \text{ miles}[/tex].
