Question

frank is drawing a treasure map using a scale of 1 cm to 10 m. he wants to show that the treasure is buried 20 m from a tree. how many cm should he show for this distance on the map? ? cm

Explanation:

Step1: Set up proportion

Let $x$ be the distance on the map in cm. The scale is 1 cm : 10 m, and the actual distance is 20 m. So the proportion is $\frac{1}{10}=\frac{x}{20}$.

Step2: Solve the proportion

Cross - multiply: $10x = 20$. Then divide both sides by 10: $x=\frac{20}{10}=2$.
