Question

What is the scale of a map if 1 cm on a map represents 20 km in real life.

Answer 1

1:20

Explanation:

well a scale is comparing one thing to another so if 1cm on a map is equal to 20 km then the scale is cm to km

1 cm to 20 km

1:20

Answer 2

0.00001:20

Explanation:

First of all, we have to realize that we are converting the scale in real life. That means, in kilometers.

So, we know that there are 100,000 cm in 1 kilometer, therefore we can know that 1 cm will equal to 0.00001 kilometers. (I divided by 1 by 100,000. Move the decimal point from 1. by six places.)

There you have the answer: 0.00001:20
