Question

A map has a scale of 1 cm : 16 km. Two cities are 5.2 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?

Answer 1

`\bf \stackrel{cm}{1}~:~\stackrel{km}{16}\qquad \cfrac{1}{16}\qquad \qquad \cfrac{\stackrel{map}{5.2}}{\stackrel{actual}{x}}=\cfrac{1}{16}\implies \cfrac{5.2\cdot 16}{1}=x`
