Answer
$\vec{v} = -.8\hat{j} \ cm/h$
$\vec{d}=-4.8\hat{j} \ cm$
Work Step by Step
The displacement is $-4.8\hat{j} \ cm$. We know this because the hand goes from positive 2.4 cm on the y axis to -2.4 cm on that axis. The velocity is given by the displacement over the change in time, which is 6 hours. This gives:
$\vec{v} = -4.8/6\hat{j} = -.8\hat{j} \ cm/h$
