Answer
Average Velocity: 0.222 m/s
Average Speed: 2.22 m/s
Work Step by Step
Average Velocity:
$\Delta s=s_C-s_A=-6-(-8)=2$
$v_{avg}=\frac{\Delta s}{\Delta t}=\frac{2}{4+5}=0.222$ m/s
Average Speed:
$s_{A \rightarrow B}=8+3=11$
$s_{B \rightarrow C}=3+6=9$
$s_{tot}=11+9=20$
$(v_{speed})_{avg}=\frac{s_{tot}}{\Delta t}=\frac{20}{4+5}=2.22$ m/s
