A mas key shows that every 5 in ches on the más representa 200 miles of actual distance. Su pose the distance between two cities on the map is 7 inches. What is the actual distance between the two cities? Write the rule you uses to find the actual ditance.

200/5 = 40/1 or 40 miles per inch.

Take it from there.

To find the actual distance between two cities using a map scale, you can use the following rule:

1. Determine the scale of the map: In this case, the scale is 1 inch represents 200 miles.

2. Measure the distance between the two cities on the map: In this case, it is given that the distance is 7 inches.

3. Multiply the measured distance on the map by the scale factor: Multiply 7 inches by 200 miles/inch.

Actual Distance = 7 inches × 200 miles/inch

4. Calculate the product:

Actual Distance = 1,400 miles

Therefore, the actual distance between the two cities is 1,400 miles.
