Answer:
12 miles
Step-by-step explanation:
In order to solve the problem you only have to use the scale of the map, we know that the ratio is 1 inch to 3 miles, so if one inch in the map represent 3 miles on real scale, now we just do a rule of three like this:
[tex]\frac{1 inch}{4 miles}=\frac{3 inches}{x}[/tex]
So now that we have our function we can clear the x to solve the problem:
[tex]x=\frac{3x4}{1}[/tex]
[tex]x=\frac{12}{1}[/tex]
[tex]x=12 miles.[/tex]
By doing this we now know that there are 12 miles from downtown to the lake.
