You measure 3 inches between two points on a 1: 24,000 scale map. the actual distance between these places in miles is:

Hello!

If the scale on a map is 1inch:24,000miles, then that means for every one inch measured on map, it equals 24,000miles in actual distance. So 3inches will equal 3 x 24,000= 72,000miles

Hope this helps! Thanks!
