the scale on a map reads 1/2 inch=75miles if the distace between two cites on the map is 3 1/4 inches find the actual distsnce between citties​
we have that
the scale is 1/2 inch=75miles
Applying proportion
75/(1/2)=x/(3 1/4)
Remember that
3 1/4=3+1/4=13/4
substitute in the proportion
75/(1/2)=x/(13/4)
solve for x
x=(75*2)*(13/4)
x=150*(13/4)
x=487.5 miles
