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 meters from a tree. How many centimeters should he show for this distance on the map?

Answer 1

Answer:

2cm

Step-by-step explanation:

Using the initial scale (ratio) of 1 cm to 10m:

$\frac{cm}{m}=\frac{1}{10}$

You can set up a proportion to solve for the amount of centimeters needed for 20 meters:

$\frac{1}{10}=\frac{x}{20}$, where 'x' is the number of centimeters

Multiplying both the numerator and denominator by '2' in the initial ratio gives you a measure of 2 cm.
