Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?
VLD [36.1K]

<u>Answer:</u>

1 cm : 10.5 km

<u>Step-by-step explanation:</u>

We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.

For this, we can use the ratio method.

\frac { 3 cm } { 1 c m } = \frac { 3 1 . 5 k m } { x }

x = \frac { 3 1 . 5 \times 1 } { 3 }

x = 1 0 . 5

Therefore, the scale of the map would be 1 cm : 10.5 km.
