We have to find the proportion can be used to find the actual distance represented by 5 inches on the map
In 3 inches = 5 miles
In 1 inch =[tex]\frac{5}{3} miles [/tex]
To find the 5 inches distance in miles we are multiplying by ratio [tex]\frac{5}{3}[/tex]
In 5 inches =[tex]\frac{5}{3}\times 5[/tex] miles
