Final answer:
To find the actual distance represented by 30 inches on the map, use the proportion 2 inches/15 miles = 30 inches/x miles. Solve for x to find that the actual distance is 225 miles.
Step-by-step explanation:
To find the actual distance represented by 30 inches on the map, you can use the proportion: 2 inches/15 miles = 30 inches/x miles.
To solve for x, cross multiply: 2x = 30 * 15.
Then, divide both sides by 2 to solve for x: x = (30 * 15) / 2 = 225 miles.
