videos 7.4c to 7.5b

Lesson 7.4 C , p398, ex 3. Read below before watching the video.

- This is a classic math problem. Click on the link below to watch a video just like example 3 on p398. Our math book uses "A" for Airplane, but in the video the teacher chose "P" for Plane. Other than this minor difference it's the exact same problem.

- Remember that the wind will affect the total speed (or ground speed or still air speed – all of these mean the same thing) of the plane.

- If Plane goes with the wind, then Total Speed = speed of Plane + speed of the Wind.... that is: S= P + W

- If Plane goes against the wind, then it will go slower, so Total Speed = speed of Plane – speed of Wind.... that is: S = P – W .

- Check out the video. It's a little complicated but hang in there. You can do it! http://www.youtube.com/watch?v=yla2bk7jB_A

Lesson 7.5 A, objective 1,

- Read p 405, ex 1, 2.

- Graphing inequalities (this is a quick, short video. Watch it more than once if needed). http://www.youtube.com/watch?v=jU1d4D8ahYY

Lesson 7.5 B, objective 2, p406, ex 3.

- Read ex 3 on p406.

- Modeling real-world situation http://www.phschool.com/atschool/academy123/english/academy123_content/wl-book-demo/ph-237s.html
