A map distance of 5 inches 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.
The actual distance is 280. To find the answer you find the unit rate which is 1/40 (1 inch for 40 miles) then multiply the given number (7) by the unit rate (40).
