Final answer:
To find the number of inches on the map that represent 10 actual miles, set up a proportion using the given scale. The answer is 25 inches.
Step-by-step explanation:
To find the number of inches on the map that represent 10 actual miles, we can set up a proportion using the given scale. The scale shows that 3 inches represents 1.2 miles.
We can set up the proportion as: 3 inches / 1.2 miles = x inches / 10 miles.
To solve for x, we can cross multiply and divide:
3 inches * 10 miles = 1.2 miles * x inches
x inches = (3 inches * 10 miles) / 1.2 miles = 25 inches
Therefore, 25 inches on the map represent 10 actual miles.
