Question 702241: 3 inches on a map represents 100. the distance between two cities is 7 1/2 inches. what is the actual distance between the cities? Answer by AFKeying(5) (Show Source):
You can put this solution on YOUR website! First, what you need to do on this problem is see how many times 3 goes into 7 1/2 (which if you see that 1 1/2 + 6 is equal to 7 1/2, you can see that 3 goes into 7 1/2 exactly 2 1/2 times).
knowing that 3 inches is 100 miles on the map, we can conclude that they are 250 miles apart (2 1/2 * 100).
