Answer:

Set up the scale as the ratio of the approximate distance on the globe, twelve inches, and the approximate actual distance between the two cities, three thousand miles. Based on these distances, the scale is twelve inches to three thousand miles which simplifies to a ratio of one inch to two hundred and fifty miles. So, one inch on the globe represents about 250 miles.
