Answer 1

To find the number of inches that represent a certain number of miles on a map, we can use the given scale and set up a proportion. Using the scale of 0.25 inches = 23 miles, we can find that 138 miles is approximately 1.725 inches.

Step-by-step explanation:

To find the number of inches that represent a certain number of miles on a map, we can use the given scale of 0.25 inches = 23 miles. The scale represents a ratio of 0.25 inches to 23 miles, so we can set up a proportion to solve the problem.

Let 'x' represent the number of inches that represent 138 miles. The proportion is:

0.25 inches / 23 miles = x inches / 138 miles

Cross-multiplying and solving for 'x', we have:

0.25 * 138 = 23 * x

x= 1.725 inches

Therefore, the number of inches that represent 138 miles is approximately 1.725 inches.
