Step-by-step 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 2

The actual distance between the two cities is 280 inches. I set up a proportion because you need to find the x amount of actual inches between the two cities.

5x= 200 x 7 or 5x = 1400 is 280/ 1400 divided by 5 is 280 actual inches.
