Question

If the actual distance between two places $A$ and $B$ is $110km$ and it is represented on a map by $25mm$. Then the scale used is ______.

Answer 1

Scale :

The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground.

Find the scale

The distance between two places $A$ and $B$ is $=110Km$.

The distance shown on the map is $=25mm$ .

Scale $=\frac{25}{110\times 1000\times 1000}$ [$\mathbf{1}\mathbf{}\mathbf{Km}\mathbf{}\mathbf{=}\mathbf{}\mathbf{1000}\mathbf{\times }\mathbf{1000}\mathbf{}\mathbf{mm}$]

Scale $=\frac{1}{4400000}$

Hence, the scale used is$\mathbf{}\mathbf{1}\mathbf{:}\mathbf{4400000}$.
