Problem

Starting from a reference point

A

, a farmer walks

60\,\text{m}

due south and then

80\,\text{m}

due east to reach point

B

. Which pair of values correctly gives the total distance travelled and the magnitude of displacement? a) Distance

=100\,\text{m}

, Displacement

=140\,\text{m}

b) Distance

=140\,\text{m}

, Displacement

=20\,\text{m}

c) Distance

=140\,\text{m}

, Displacement

=100\,\text{m}

d) Distance

=100\,\text{m}

, Displacement

=60\,\text{m}
