a plane has an airspeed of 200 mph. the pilot wants to reach a destination 600 miles east but a wind is blowing 50 mph 30 degrees North of East. What direction must the pilot head the plane in order to reach the destination?
I asked my Lab T.A. and she helped me understand that I basically need to draw two vectors and get the average of the two but all of my answers are wrong so far...

kristen,
Not the average of the two  you need to find the vector which, when added to the windspeed vector, will give the vector to the desired destination. So you are really subtracting vectors. Try that....

Physics 
Alura,
It's still confusing me...200mph50 gives us 150mph but how do i know the angle of that vector? I know it's South of East...

Physics 
Alura,
nevermind! got it! thanks!

Physics 
kristen,
way to be persistent! now you probably won't forget how it's done, since you worked so hard.
