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

answer is 487.5 miles
