Answer:
40 cm.
Step-by-step explanation:
Let x be the distance between two villages on map.
We have been given that the actual distance between two villages is 120 kilometers. On a map of the area, 1 centimeter represents 3 kilometers.
We will use proportions to find the distance between villages on the map as proportion states that two fractions are equal.
[tex]\frac{\text{Distance on map}}{\text{Actual distance}}=\frac{\text{1 cm}}{\text{3 km}}[/tex]
Upon substituting the actual distance between the two villages in our proportion we will get,
[tex]\frac{x}{\text{120 km}}=\frac{\text{1 cm}}{\text{3 km}}[/tex]
Let us multiply both sides of our equation by 120 km.
[tex]\frac{x}{\text{120 km}}*\text{120 km}=\frac{\text{1 cm}}{\text{3 km}}*\text{120 km}[/tex]
[tex]x=\frac{\text{1 cm}}{3}*120[/tex]
[tex]x=\text{1 cm}*40[/tex]
[tex]x=\text{40 cm}[/tex]
Therefore, the distance between two villages on the map is 40 cm.
