Question

On a map, 1 cm represents 3 km. The real-life distance between two towns is 27 km. What is the distance between these two towns on a map?

Answer 1

9cm

Explanation:

1:3 this is the starting ratio

if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.

Answer 2

9 cm

Explanation:

Every centemeter represents three. 3km=1cm.

The number of kilometers/3= the number of centemeters.

the number of centemeters x 3= the number of kilometers.

We now have three equations to help us covert back and forth.

The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)

The number of kilometers/3= the number of centemeters.

27/3=the number of centemeters.

Thus, the answer is nine.
