Map Distances and Scale Factors

This video tutorial explains how to use proportions to solve application problems. It includes two examples: one involving a park hiking map to find the actual distance using a given scale, and another to calculate the scale factor for a map. The tutorial demonstrates setting up proportions, simplifying equations, and solving for unknowns using cross-multiplication and clearing fractions.

What is the scale factor used in the first example of the park hiking map?

• 1 to 12

• 1 to 8

• 1 to 5

• 1 to 10
