Question

chaya has a map that shows
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
waterfall
parking
picnic
area
6 cm
9 cm
ranger
tower
3 cm: 1.5 km
3 cm

Explanation:

Step1: Find the scale factor

Given the scale \(3\ cm:1.5\ km\). To find the number to multiply the map distance by, divide the actual distance by the map distance. So, \(\frac{1.5}{3}=0.5\).

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 scale factor \(0.5\) (from Step 1), multiply the map distance by the scale factor. The formula is \(Actual\ distance=Map\ distance\times Scale\ factor\). So, \(9\times0.5 = 4.5\)

Answer:

\(4.5\)
