How do you figure the mileage between cities?

To figure the mileage between two cities using a map, locate each city on the map and then use a ruler to draw a straight line between the cities. Use the map scale to convert the measured distance into miles.

If driving miles between the two cities are needed instead of flying miles, use the same method with the ruler and scale, but plot the distance along the roads. Add up the total distance traveled and use the scale to convert to miles. For example if the distance between to cities is 1.5 inches and the scale is 1 inch equals 100 miles, the distance between the two cities is 150 miles.
