Ground speed/ air speed help

[baileighgentry]

the heading of an airplane is 250 degrees. a 40 km/hr wind is blowing toward 320 degrees, causing the plane to move the direction 255 degrees. what is the air speed and ground speed of the plane?

Your drawing doesn't make sense. Why is the line pointing 40 degrees from the horizontal? Don't we need the speed of the plane too?

Edit: I see why it's 40 degrees...

The heading of the wind is 320 degrees, which forms a 40 degree angle

No; the wind is not erupting from the ground and heading skyward at an angle of forty degrees. Return to your book and look at similar examples. What does a "heading" of a particular angle mean? (Hint: Compass points.)
