    In this kind of vector additions, we use Pythagorean theorem, which is √(Vx² + Vy²)

    If we use it, the velocity is found to be √(-3.1² + 6.5²) ≅ 7.20 m/s

    And when it comes to the direction, I want you to think of coordinate system and a compass. X coordinate is negative and Y coordinate is positive. The direction is northwest (not strictly).

    If you think anything is wrong, or you have anything that you do not understand, please let me know. I am sorry for my bad English by the way ^^
