(SCALE: 2 100 iph
The combination of the velocities of wind and the Eircraft is the resultant velocity whion. ta`200 m.p.h.j and is represented by AB, 4 inches. A represent. The velocity of the Hind, 50 m.p.h.
þat Construct a parallelogram with AB as the diagonaly and AC being one of the vides. The side AD so
constrasted represents the velocity of the aircraft.
