A map of the eastern United States has a scale
where 3 inches = 25 miles. If the distance on the map
between Columbia, South Carolina, and Charlotte, North Carolina, is 11.5 inches what is the actual distance between the cities?
Using the scale 3 inches = 25 miles, we can set up a proportion:
3 inches / 25 miles = 11.5 inches / x
Cross-multiplying, we get:
3 inches * x = 25 miles * 11.5 inches
Dividing both sides by 3 inches, we get:
x = (25 miles * 11.5 inches) / 3 inches
x = 95.833 miles
Therefore, the actual distance between Columbia, South Carolina, and Charlotte, North Carolina is approximately 95.833 miles.
