Scale diagrams
It is given that 2 centimeters on the map represents 3 kilometers of actual length.
[tex]2\ \text{centimeters}=3\ \text{kilometers}[/tex]
We need to find what 1 centimeter on the map represents.
So, we divide both sides by 2.
[tex]\dfrac{2}{2}\ \text{centimeters}=\dfrac{3}{2}\ \text{kilometers}=1.5\ \text{kilometers}[/tex]
The length of the trail is 4.5 centimeters in the map. So,
[tex]4.5\ \text{centimeters}=4.5\times 1.5=6.74\ \text{kilometers}[/tex]
