Answer:
[tex]18\ miles[/tex]
Step-by-step explanation:
we know that
The scale on a map is equal to
[tex]\frac{2.5}{10}\frac{inches}{miles}[/tex]
so
by proportion
Find the actual distance between the historical markers
Remember that on a map, the distance between two historical markers is [tex]4.5[/tex] inches
[tex]\frac{2.5}{10}\frac{inches}{miles}=\frac{4.5}{x}\frac{inches}{miles}\\ \\x=10*4.5/2.5\\ \\x= 18\ miles[/tex]
