A map’s scale is 1 inch: 3.5 miles. If the actual distance between two places is 77 miles, then they will be inches away from each other on the map.

Work Shown:

(1 inch)/(3.5 miles) = (x inches)/(77 miles)

1/3.5 = x/77

1*77 = 3.5*x cross multiply

77 = 3.5x

3.5x = 77

x = 77/3.5

x = 22

22 inches on paper correspond to 77 miles in real life.
