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

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

Answer 2

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

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 =
`(4)/(5) cm`

4 km =
`(4)/(5) * 4 cm`

4 km =
`3.2 cm`

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