Shows how to solve a word problem involving the rate of a wind and flying in still air using 2 variables and 2 linear equations.
- If a jet flying with a tailwind traveled 1680 miles in 3 hours, and flying against the wind, it traveled 1960 miles in 4 hours, what is the rate of the jet in still air and the rate of the wind?
- How do can you make a chart to help you solve a rate of wind word problem?
- How do you solve a rate of wind word problem using systems of equations?
- How do you set up a system of equations from a word problem?
- How do you check your answer to a system of equations word problem?
- Is there an easy way to find the rate of a plane and the rate of the wind when a plane travels with the wind and against the wind?
- How do you solve a word problem about a plane traveling with the wind and against the wind?
- How do you solve the system of equations 3(x + w) = 1680 and 4(x - w) = 1960?
This is a great tutorial video on how to solve wind word problems in Algebra by writing a system of equations from the situation. A chart is used to set up the problem as well, and the solution is checked using the original problem. Two full solutions are shown in this video.
