On a map, the distance between two towns is 3.4 inches. The map scale is 2 inches: 25 miles. What is the actual distance between these towns?

Respuesta :

For this question we can solve it by setting up a proportion:

[tex] \frac{2inches}{25 miles}= \frac{3.4inches}{x} [/tex]

Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:

[tex]2x=85[/tex]
[tex]x=42.5miles[/tex]

So now we know that the total distance between the towns is 42.5 miles.
