Solution:
a) The vector equation for the velocity of the plane with respect to
the wind is given by,
V_{pw} = V_{pg} + V_{gw}
b) We can now draw the vector diagram the represents the vector equation.
Note the reversal of the velocity vector, wind w.r.t. ground, V_{wg}.
This satisfies the vector equation and ensures the addition of the vectors
in the tiptotail convention.

The heading is thus given by 6.8^{0} + 24^{0} = 30.8^{0}
West of North
