where Vpg = 1000 km / 2.5 hr at 450 North of East
Vpg = 400 km/hr 450 North of East
Vwg = 75 km/hr at 700 South of East
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, Vwg.
This satisfies the vector equation and ensures the addition of the vectors
in the tip-to-tail convention.
