The position vector of the particle at time $t = 0$ is ${\vec{r}}_{i} = 2 \hat{i} + 3 \hat{j}$
The position vector of the particle at time $t = 5 s$ is ${\vec{r}}_{f} = 13 \hat{i} + 14 \hat{j}$
The displacement of the particle is $\vec{s} = 11 \hat{i} + 11 \hat{j}$
The average velocity vector $〈\vec{V}〉 = \frac{11 \hat{i} + 11 \hat{j}}{5}$
