Question

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 waterfall trail? km 3 cm:1.5 km

Explanation:

Step1: Determine the scale factor

The scale is $3\ cm:1.5\ km$. First, convert $1.5\ km$ to $150000\ cm$. The scale factor is $\frac{150000}{3}=50000$. So we multiply each distance in the scale - drawing by 50000 to get the actual distance.

Step2: Calculate the actual length of the waterfall - trail

The length of the waterfall - trail in the scale drawing is $6\ cm$. Multiply it by the scale factor. The actual length $d = 6\times50000 = 300000\ cm$. Convert $300000\ cm$ to $km$. Since $1\ km = 100000\ cm$, then $d=\frac{300000}{100000}=3\ km$.
