Smithville if they are 0.8 cm apart on a map with a scale of 1 cm : 17.7 km .
$\square$
Solution
Solution Steps
Step 1: Understand the scale of the map
The map scale is given as \( 1 \, \text{cm} : 17.7 \, \text{km} \). This means that every \( 1 \, \text{cm} \) on the map represents \( 17.7 \, \text{km} \) in real life.
Step 2: Determine the distance on the map
The distance between Rivertown and Smithville on the map is \( 0.8 \, \text{cm} \).
Step 3: Calculate the real-life distance
Multiply the map distance by the scale to find the real-life distance:
\[
\text{Real-life distance} = 0.8 \, \text{cm} \times 17.7 \, \text{km/cm} = 14.16 \, \text{km}.
