$v = 3, 8 m/s (the green vector shows direction)$ $v=3,8" m/s (the green vector shows direction)"$

Explanation:

$displacement between the Points A and B :$ $"displacement between the Points A and B :"$
$Delta s=sqrt(9^2+7^2)$
$Delta s=sqrt(81+49)$
$Delta s=sqrt130$
$Delta s=11,40 " m"$

$v=(Delta s)/(Delta t)$

$v=(11,40)/3$

$v=3,8" m/s (the green vector shows direction)"$
