Question

The scale of a map says that 4 cm represents 5 km.

What distance on the map (in cm) represents an actual distance of 20 km?

Answer 1

16 cm

Explanation:

4 cm represents 5 km. There is a total length of 20 km, so you do 20/5=4. Since you have to multiply 5 by 4 to get 20, you also multiply 4cm by 4, and you get 16, or the amount of cm that represents 20 km.
