An airplane is flying north with an airspeed of 200 km/h when it encounters a crosswind of 70 km/h toward the east. which expression gives the resultant speed of airplane?

Sagot :

Answer:

211.89 km/h

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 :

[tex]v=\sqrt{200^2+70^2} \\\\=211.89\ km/h[/tex]

So, the required speed is 211.89 km/h.
