the scale on a map is 2 cm=25 miles. Dave measured the distance to the next town at 5cm. Hoiw many miles away is the next town?

[tex]\bf \begin{array}{ccll} \stackrel{cm}{map}&\stackrel{miles}{actual}\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 2&25\\ 5&x \end{array}\implies \cfrac{2}{5}=\cfrac{25}{x}\implies x=\cfrac{5\cdot 25}{2}[/tex]
