Question

choya has a map that shows the lengths of some hiking trails. the scale is shown in the drawing.
what number can you multiply each distance in
the scale drawing by to find the actual distance?
0.5
what is the actual length of the picnic area trail?

km

Explanation:

Step1: Find the scale factor

Given the scale \(3\ cm:1.5\ km\). To find the multiplier, divide the actual distance by the map distance. So, \(\frac{1.5}{3}=0.5\). This means each centimeter on the map represents \(0.5\) km in actual.

Step2: Calculate the actual length of the picnic - area trail

The length of the picnic - area trail on the map is \(9\ cm\). Using the multiplier \(0.5\) (from Step 1), the actual length \(L\) is \(L = 9\times0.5\).

Answer:

\(4.5\)
