The table shows the position of a cart moving along a straight track. Time

t

(s): 0 2 5 8 Position

x

(m): 0 4 4 −2 Find: (i) the average velocity from

t = 0\,\text{s}

t = 2\,\text{s}

, (ii) the average velocity from

t = 2\,\text{s}

t = 5\,\text{s}

, (iii) the average velocity for the entire interval from

t = 0\,\text{s}

t = 8\,\text{s}
