The correct answer to the question is : 10 m/s , northwest.

EXPLANATION:

As per the question, the velocity of wind V = 8 m/s towards north.

      The velocity of the paper airplane is V' = 6 m/s towards west.

We are asked to calculate the actual velocity of the airplane.

By putting Pythagorean theorem, the actual velocity of the airplane is calculated as -

                  V_{net}^2 =\ V^2+V'^2

                ⇒  V_{net}^2=\ 6^2+8^2

                ⇒  V_{net}^2\ =\ 100

                ⇒  V_{net}=\ \sqrt{100}\ m/s

                ⇒  V_{net}=\ 10\ m/s  towards northeast.

Hence, the correct answer is 10 m/s , northwest.
