The line XY below is drawn to scale and represents the distance between Khalid's shop and Ole Sankale's hardware. If the actual distance is 900 m, what is the scale used to make the drawing in ratio form?

The actual distance between Khalid's shop and Ole Sankale's hardware is $900 \text{ m}$.
By measuring the line XY directly from the image, its length is approximately $3.6 \text{ cm}$.

Since $1 \text{ m} = 100 \text{ cm}$:

actual length).

Divide both sides of the ratio by 3.6:

The scale used to make the drawing is $1:25000$.
