    In position #1, at time t₁ = 0, the coordinates are (1.1 m, 3.4 m).

    That is,

    x₁ = 1.1 m, y₁ = 3.4 m.

    In position #2, at time t₂ = 3.0 s, the coordinates are (5.3 m, - 0.5 m).

    That is,

    x₂ = 5.3 m, y₂ = - 0.5 m.

    The x-component of the average velocity is

    Vx = (x₂ - x₁) / (t₂ - t₁)

    = (5.3 - 1.1 m) / (3 - 0 s)

    = 1.4 m/s

    Similarly, the y-component of the average velocity is

    Vy = (-0.5 - 3.4) / 3

    = - 1.3 m/s

    Answer

    The x and y components of the average velocity are 1.4 m/s and - 1.3 m/s respectively.
