  1. D(X,Y) = D(1130,-950)m.

    tanA = Y/X = -950/1130 = -8407,
    A = -40.05 Deg, CW = -40.05 + 360 = 320
    Deg, CCW.

    D = X/cosA = 1130 / cos320 = 1475m @
    320 deg = Displacement.

    t = 22min * 60s/min = 1320s.

    V = D/t = 1475m @ 320deg / 1320s =
    1.12m/s @ 320deg.

    V(h) = 1.12cos320 = 0.856m/s = hor comp. of Velocity.

    V(v) = 1.12sin320 = -0.720m/s = ver
    comp of Velocity.

    V(X,Y),
    V(0.856,-0.720).
