Morgarella [4.7K]

Answer:

The actual distance between the historical markers is 18 miles.

Step-by-step explanation:

Given : On a map, the distance between two historical markers is 4.5 inches, and 2.5 inches represents 10 miles.

To find : What is the actual distance between the historical markers?

Solution :

We have given that,

2.5 inches represents 10 miles.

i.e, 1 inch represent $\frac{10}{2.5}$ miles.

1 inch = 4 miles.

Now, The distance between two historical markers is 4.5 inches.

The actual distance between the historical markers in 4.5 inch is

$4.5 \text{ inch}=4.5\times 4\text{ miles}$

$4.5 \text{ inch}=18\text{ miles}$

Therefore, The actual distance between the historical markers is 18 miles.
