Work Step by Step

A scale drawing is a drawing that is similar to an actual object or place. Floor plans, blueprints, and maps are all examples of scale drawings. In a scale drawing, the ratio of any length on the drawing to the actual length is always the same. This ratio is called the scale of the drawing. a) Map Scale =$\frac{map \:distance}{actual\: distance}$ $\frac{1}{100}$=$\frac{0.6}{x}\\ x=100*0.6\\ x=60$ The actual distance from Jacksonville to Gainesville is 60 mi. b) Map scale is simply the ratio of map distance and actual distance. Map Scale =$\frac{map \:distance}{actual\: distance}$ Map Scale =$\frac{2}{250}$ 1 in : 125 mi
