Question

A map's key shows that every of 5 inches on the map represents 200 miles of actual distance. Suppose the distance between two cities on the map is 7 inches. What is the actual distance between the two cities? Write the rule you used to find the actual distance.

Answer 1

First you would work out what 1 inch represents. To do this you would divide 200 by 5 to get 40. So, 40 miles is 1 inch, making 280 miles, 7 inches.
