+36916 y component of plane = 650 there is no x component w/out wind
y component of wind = 60 sin -45 = -42.42
x component of wind =60 cos-45= 42.42
Add components x's and y's
y = 650-42.42 =607.58
x= 42.42
Angle = arctan 607.58/42.42 = 86 degrees (4 degrees off course to the east)
Airspeed over ground = sqrt(607.58^2 + 42.42^2) = 609 km/hr
Please help.
