<PRE><B>Question 391010</B>
Assuming 650 km/hr is the air speed:
{{{Ground speed = sqrt(650^2 + 35^2)}}}
=~ 650.94 km/hr
or ~ 651 km/hr
---------------
Its ground track is 270º + arctan(35/650)
=~ 273.1º
You asked for velocity.  Velocity is a vector with components of speed and direction.
---------------
PS Aviation and weather people us knots for speed, not km/hr or miles/hr.
