Problem

A car travels 120 m120\,\text{m} east, then 70 m70\,\text{m} west in a straight line. Taking east as positive, choose the correct pair (distance travelled, displacement)(\text{distance travelled},\ \text{displacement}). (a) (50 m, +50 m)(50\,\text{m},\ +50\,\text{m}) (b) (190 m, +50 m)(190\,\text{m},\ +50\,\text{m}) (c) (190 m, −50 m)(190\,\text{m},\ -50\,\text{m}) (d) (50 m, +190 m)(50\,\text{m},\ +190\,\text{m})
