Question

An elementary school in Lancaster gets its school supplies from the district office, 3kilometers away. On a map with a scale of 2 centimeters: 1 kilometer, how far apart are theelementary school and the district office?

Answer 1

Since 2 cm on the map represents 1 km in real

Since the real distance is 3 km, then

$\frac{2}{1}=\frac{x}{3}$

Where x is the distance on the map

$\begin{gathered} 1\times x=2\times3 \\ x=6 \end{gathered}$

The distance on the map is 6 cm
