Problem

A walker starts from his home and follows this route:

200\,\text{m}

east,

150\,\text{m}

north,

120\,\text{m}

west, and finally

150\,\text{m}

south. He then stops. Which statement correctly gives both the total distance travelled and the magnitude of his displacement? (a)

\text{Distance} = 620\,\text{m},\ \text{displacement} = 0\,\text{m}

(b)

\text{Distance} = 470\,\text{m},\ \text{displacement} = 80\,\text{m}

(c)

\text{Distance} = 620\,\text{m},\ \text{displacement} = 80\,\text{m}

(d)

\text{Distance} = 620\,\text{m},\ \text{displacement} = 200\,\text{m}
