Question

Approximately how many kilometers are represented by $1°$ of latitude.

Answer 1

Convert latitude into kilometers:

Each degree in latitude is $69\mathrm{miles}$ apart.

Convert $1°$ latitude into kilometers as follow:

$$\begin{gathered} 1°\mathrm{of}\mathrm{latitude}=69\mathrm{miles} \\ =69\times 1.60934\mathbf{}\left[\because 1\mathrm{miles}=1.60934\mathrm{km}\right] \\ =111.04\mathrm{km} \end{gathered}$$

Hence, there is approximately $111\mathrm{km}$ in $1°$ of latitude.
