An aeroplane x whose average speed is 500km lives kano air port at 7am and travels no a bearing of 50degree it then changes it course it an air strife on a bearing of 120degree to an airport A . another aeroplane Y lives kano and
Incomplete problem statement, will try to help.
Heading 50 deg clockwise from North (40 up from x axis East) for time t1
then 120 (30 below + x axis) for time t2 to A
x (East) distance = 500 t1 cos 40 + 500 t2 cos 30
y (North)distance= 500 t1 sin 40 - 500 t2 sin 30
