Answer:

211.89 km/h

Step-by-step explanation:

Given that,

The speed of an airplance in North direction = 200 km/h

Speed in East direction = 70 km/h

We need to find the resultant speed of the airplane. It can be calculated as the resultant of the two velocities as follows :


v=√(200^2+70^2) \\\\=211.89\ km/h

So, the required speed is 211.89 km/h.
