Two villages are 14km apart in real life. How far apart would they be on A map scale with 1:25000

nydimaria [60]

Given:

Distance between two villages = 14 km

Map scale = 1:25000

To find:

The distance between the two villages on the map.

Solution:

Let the distance between the two villages on the map be x.

Map scale is 1:25000. So,

$\dfrac{x}{14}=\dfrac{1}{25000}$

$x=\dfrac{1}{25000}\times 14$

$x=0.00056$

Therefore, the two villages are 0.00056 km apart on map.
