The distance between the cities is 280 miles. The rule is y = 40x, where x is the distance in inches on the map and y is the distance in miles.

Step-by-step explanation:

Step 1:

The map's key shows that 5 inches on the map equal 200 miles of actual distance.

5 inches on the map = 200 miles of actual distance,

if we divide both sides by 5, we get;

1 inch on the map = 40 miles of actual distance.

Step 2:

If x is the distance on the map in inches and y is the actual distance in miles,

y = 40x.

If the map distance 7 inches, x = 7.

Substituting, x =7 in the equation,  .

So the actual distance between the cities is 280 miles.
