###### Question:

## Answers

10/4=x/20

Your answer will be x=50 kilometers

The required proportion is

[tex]\dfrac{10}{4}=\dfrac{x}{20}.[/tex]

Step-by-step explanation: Given that the scale on a map shows that 10 kilometers is represented by 4 centimeters.

We are to find the proportion can be used to find the actual distance, x, represented by 20 centimeters on the map.

We have

4 centimeters on the map = 10 kilometers.

So, 1 centimeter on the map [tex]=\dfrac{10}{4}~\textup{kilometers}.[/tex]

Also,

20 centimeters on the map = x kilometers.

So, 1 centimeter on the map [tex]\dfrac{x}{20}~~\textup{kilometers}.[/tex]

Therefore, we must have

[tex]\dfrac{10}{4}=\dfrac{x}{20}.[/tex]

Thus, the required proportion is

[tex]\dfrac{10}{4}=\dfrac{x}{20}.[/tex]

8 kilometers

Step-by-step explanation:

you get your unit rate by dividing 10/4 = 2.5 then you divide 20 by 2.5
