$see animation$ $"see animation"$
$the velocity of B from perspective of A : v = 3, 16 m/s$ $"the velocity of B from perspective of A :" v=3,16" m/s"$

Explanation:

$Delta x=-6-3=-3" m"$
$Delta y=-1-8=-9" m"$
$"displacement between the points A and B:"$
$a=sqrt(Delta x^2+Delta y^2)$
$a=sqrt((-3)^2+(-9)^2)$
$a=sqrt(9+81)$
$a=sqrt90$
$a=9,49" m"$
$v=a/(Delta t)$
$v=(9,49)/3$
$v=3,16" m/s"$
