Problem

A girl starts at one vertex of an equilateral triangle with side 40 m40\,\text{m}, walks along all three sides to return to the starting point, and then repeats the entire trip once more. Which option gives the correct pair (distance, displacement)(\text{distance},\,\text{displacement}) for her motion at the end of the second trip? a) (120 m, 0 m)(120\,\text{m},\,0\,\text{m}) b) (240 m, 40 m)(240\,\text{m},\,40\,\text{m}) c) (240 m, 0 m)(240\,\text{m},\,0\,\text{m}) d) (120 m, 40 m)(120\,\text{m},\,40\,\text{m})
