\begin{gathered} \text{Scale factor = 1:1400000} \\ 1\operatorname{cm}\text{ represent 14km} \end{gathered}Step-by-step explanation:

Distance from airport to his cousin's house = 56km

The distance on the map = 4cm


\begin{gathered} 4\operatorname{cm}\text{ = 56km} \\ 1\text{ cm = 56/4} \\ 1\text{ cm = }14\operatorname{km} \end{gathered}
\text{This means 1cm on the map represent 14km in real life distance}
\begin{gathered} 14\operatorname{km}\text{ = 14}*1000*100\operatorname{cm} \\ 14\operatorname{km}\text{ = 1400000cm} \\ The\text{ scale factor = 1cm : 14km = }1\operatorname{cm}\text{ :1400000cm} \\ \text{The sclae factor = 1:1400000} \end{gathered}
