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
