In this lesson, we explore how to set up and solve proportions using a real-world example involving Meagan's jogging routine. Meagan jogged 2 miles in 30 minutes, and we will determine how many miles she can jog in 90 minutes by forming a proportion. By cross-multiplying and simplifying the equation, we can easily find that Meagan can jog 6 miles in 90 minutes. This problem illustrates the practical application of proportions in everyday situations.
