Final answer:
Using a map scale of 1 inch = 500 miles, cities 3000 miles apart would be 6 inches apart on the map.
Step-by-step explanation:
To determine the distance on a map between two cities that are 3000 miles apart using a scale of 1 inch = 500 miles, you can set up a proportion. The proportion will compare the map distance to the actual distance, using the scale provided. So, if 1 inch represents 500 miles, then x inches will represent 3000 miles.
The proportion will look like this:
1 inch / 500 miles = x inches / 3000 miles
To solve for x, the number of inches on the map, you can cross-multiply and divide:
(1 inch * 3000 miles) / 500 miles = x
x = 3000 / 500
x = 6
Therefore, cities that are 3000 miles apart are represented as 6 inches apart on this map.
