On a map, the distance between village A and village B measures 6 centimeters and the distance between village A and village C measures 9 centimeters. The actual distance from village A to village B is 20 kilometers. If the distance between two points on a map is directly proportional to the actual distance between the locations, how far is it from village A and village C in kilometers?
Using the idea of ratio and proportion you'll have the distance from A to C as [tex] \frac{AC}{9cm} = \frac{20km}{6cm} [/tex] [tex]AC = \frac{(20km)(9cm)}{6cm} [/tex] cm will cancel out AC = 30km
