Watch Video on Wind and Current Problems – Algebra Help
By admin on Mar 11, 2010 with Comments 14
Access full lesson containing this video at: www.yourteacher.com 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.

Thanks teach, you just killed the 3 different algebra teachers i have had over the years. kudos.
I LOVE YOU!!!!
Thank you very much!
thank you SO much. I can’t believe how clear and concise you are. It’s a shame that a $150 math book fails to provide examples such as this for the exercise problems its authors and a lousy teacher expect me to solve, but I’m glad you’re here. Thanks again.
thanks this was such a helpful video im going back to school in a week and that reminded me of all the math we did in 8th grade
that was beautiful
omg thank u! keep making math videos
That was absolutely brilliant! 5 stars for you!!
Cool, where is your (home) school?
my school(home school)has you as link
i was totally stuck, thanks so much
Thanks, i understand it now.
Thanks
I get it now
