Problem

A student walks

600\,\text{m}

north in

5\,\text{min}

and then

600\,\text{m}

south in

10\,\text{min}

along the same straight path. What is the magnitude of his average velocity for the entire walk? a)

1.33\,\text{m\,s}^{-1}

0.67\,\text{m\,s}^{-1}

0\,\text{m\,s}^{-1}

1.50\,\text{m\,s}^{-1}
