You didn't say so, but we must assume that the "200 km/hr" is
the glider's air-speed, that is, speed relative to the air.

If the air itself is moving at 30 km/hr relative to the ground and
across the glider's direction, then the glider's speed relative to
the ground is

   √(200² + 30²)

   = √(40,000 + 900)

   = √(40,900) = 202.24... km/hr (rounded)
