The scale on a map reads 12 inches = 500 kilometers. If the distance between Sacramento, CA and Washington D.C. is 96 inches on the map, what is the actual distance between these two locations?

Respuesta :

4,000 kilometers because, 96 divided by 12 equals 8 then, 8 times 500 equals 4,000
The answer is:  " 4,000 km " .
____________________________________
                12:500 :: 96:x  ;  Solve for "x"
___________________________________
                12/500 = 96/x  ;

                12x = (500)*(96) ;

Divide each side of the equation by "12" ;

12x / 12 = [ (500) * (96) ] / 12

           x = 500 * 8  = 4,000  ;
