In this lesson, we learn how to solve word problems using systems of equations. We focus on problems that involve planes flying against or with the wind, and we use a chart to keep track of the information. We define the rate of the plane in calm air and the rate of the wind as two variables, and we use the formula rate times time equals distance to create two equations. We then solve for the variables using the addition or subtraction method and check our answers to ensure they make sense.
