Question

The scale of a map says 4cm represents 5km what distance on the map (in centimeters) represents an actual distance of 4 km?

Answer 1

Answer:

3.2 cm on the map (in centimeters) represents an actual distance of 4 km

Step-by-step explanation:

The scale of a map says 4cm represents 5km

We are supposed to find  what distance on the map (in centimeters) represents an actual distance of 4 km

5 km = 4 cm

1 km = $\frac{4}{5} cm$

4 km = $\frac{4}{5} \times 4 cm$

4 km = $3.2 cm$

Hence 3.2 cm on the map (in centimeters) represents an actual distance of 4 km

Answer 2

To answer this question, you can set up a proportion that illustrates the map scale against the true distance.

4cm/5km=x/4km

16=5x

3.2cm=x
