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? waterfall parking 6 cm 9 cm picnic area 3 cm ranger tower 3 cm : 1.5 km

Explanation:

Step1: Analyze the scale

The scale is $3\ cm:1.5\ km$. We want to find the multiplier from map - distance (in cm) to actual distance (in km).

Step2: Calculate the multiplier

We know that if the scale is $a\ cm:b\ km$, the multiplier $k=\frac{b}{a}$. Here $a = 3$ and $b = 1.5$. So $k=\frac{1.5}{3}=0.5$.

Answer:

$0.5$
