Wind and Current Problems - YourTeacher.com - Algebra Help

For a complete lesson on wind and current problems, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve wind and current word problems using a system of linear equations, as demonstrated in the following problem. Into a headwind, the plane flew 2000 miles in 5 hours. With a tailwind, the return trip took 4 hours. Find the speed of the plane in still air and the speed of the wind. The two variables used in this problem are p, the speed of the plane in still air, and w, the speed of the wind. So the speed of the plane with a tailwind can be represented as p + w, and the speed of the plane against a headwind can be represented as p -- w. Note that this problem requires a chart to organize the information. The chart is based on the formula rate times time = distance. The chart is then used to set up the two equations.

@klmguy96 Remember that he chose "P" as his variable for the speed of the plane. Once he solved it all out he got P=450. Then once you get that answer you also have to find the speed of the wind, which he named "w". You take the answer of 450 and plug it back into one of the equations.
