Question

the scale on a map is stated as 1:250000 two villages are 9 cm apart on the map how far from each other are the two villages in kilometres

Answer 1

22.5 kilometers

Explanation:

we know that

The scale drawing is

`1:250,000`

That means

1 unit on a map represent 250,000 units in the actual

or

1 cm on a map represent 250,000 cm in the actual

or

1 cm on a map represent 2,500 m in the actual

or

1 cm on a map represent 2,5 km in the actual

therefore

using proportion

Find out how much represent 9 cm apart on the map

`(1)/(2.5)\ (cm)/(km)=(9)/(x)\ (cm)/(km)\\\\x=9(2.5)\\\\x=22.5\ km`
