Before I get to the problem, Id just like to say a big thank you to all of you who help out and answer all of our questions. While many of them appear basic, to us they are daunting. It's nice to have a place to turn to when your professor barely speaks english and isn't a whole lot of help explaining the problem. So, many thanks to all of you who set aside your time to help the less knowledgable.
Down to the problem. City A lies due West of city B. A pilot normally makes the 5310km ROUND trip in 6.6hours. One day there is a steady wind blowing from west to east and it takes the pilot 6.7 hours to make the round trip. How fast is the wind blowing.
I've spent a while on this problem and can't seem to get it.
It makes sense to me that if your wind slows you one way, it would speed you up the other way, thereby canceling out the winds effects.
Not having any formulas to really draw upon, I came up with one for the planes velocity. 804.55 normally, so it would be 804.55 - w in one direction and 804.55 + w in the opposite. Doing vector addition canceled out the W. A little lost.
