Question

what number can you multiply each distance in the scale drawing by to find the actual distance?
what is the actual length of the picnic area trail?
km

Explanation:

Step1: Find the scale factor

Given \(3\ cm = 1.5\ km\), so the scale factor \(k=\frac{1.5}{3}=0.5\ km/cm\).

Step2: Calculate the actual length of the picnic area trail

The length of the picnic - area trail in the drawing is \(9\ cm\). Using the scale factor, the actual length \(L = 9\times0.5\).

Answer:

\(4.5\ km\)
