Question

The distance between two streets is 12 centimeters. if the two streets are actually 2/3 of a mile apart ,what is the scale on the map?

please help me!!!!

Answer 1

18 cm. = 1 mi

Explanation:

12/(2/3) mi. = 12 cm. divided by 2/3 mi.

12 cm. divided by 2/3 mi. =

12 cm. times 3/2 mi. = 18 cm./ 1 mi.

So the scale is 18 cm. to 1 mi.

Answer 2

`\bf \cfrac{\stackrel{model}{cm}}{\stackrel{actual}{miles}}\qquad \cfrac{~~12~~}{(2)/(3)}\implies \cfrac{12}{1}\cdot \cfrac{3}{2}\implies \cfrac{18}{1}~\hspace{5em}\stackrel{cm}{18}~:~\stackrel{mile}{1}`
