Calculating the Actual Distance Between Two Cities Using a Map Scale
<p>Let the actual distance between the two cities be \( D \) miles.</p>
<p>The map scale provided is \( 1 \text{cm} = 20 \text{mi} \).</p>
<p>The cities are 0.5 centimeters apart on the map.</p>
<p>Using the scale, we can write the relation as follows:</p>
<p>\( 1 \text{cm} \text{ on map} = 20 \text{ mi in actual distance} \)</p>
<p>Hence, \( 0.5 \text{cm} \text{ on map} = 0.5 \times 20 \text{ mi in actual distance} \)</p>
<p>So, \( D = 0.5 \times 20 \)</p>
<p>\( D = 10 \)</p>
<p>Therefore, the actual distance between the two cities is \( 10 \) miles.</p>
