on a map the distance between two historical markers in 4.5 in in 2.5 in inches represents 10 mi what is the actual distance between the historical markers

The actual distance is 16 miles.

Step-by-step explanation:

In order to find this, create a proportion. On the left you should put the scale factor. On the right you should put the markers.

2.5in/10mi = 4.5in/xmi

Now cross multiply to solve.

10mi * 4.5in = 2.5in * xmi

45 = 2.5x

16 mi = x

Answer:the actual answer is 18 miles. I just did the test
