This lesson shows how to solve a word problem involving the rate of wind and flying in still air using two variables and two linear equations. The teacher walks through the traditional method for solving these types of problems, and then shows an alternative way of thinking about the problem. By the end of the lesson, the learner will know how to find the rate of the jet in still air and the rate of the wind, and how to check their answers.
