Answer: There are 45 miles that she have to travel to get to the next down.
Step-by-step explanation:
Since we have given that
1 inch = 15 miles
If there are given 3 inches.
We need to find the number of miles she have to travel to get to travel to get to the next town.
So, it becomes,
[tex]\dfrac{1}{15}=\dfrac{3}{x}\\\\x=15\times 3\\\\x=45\ miles[/tex]
Hence, there are 45 miles that she have to travel to get to the next down.
