Problem

A car travels 50 m east, then 30 m east, and finally 60 m west along the same straight road. Find (i) the total distance covered and (ii) the displacement from the starting point. (a) (i)  140 m,  (ii)  80 m east(i)\;140\,\text{m},\; (ii)\;80\,\text{m east} (b) (i)  140 m,  (ii)  20 m west(i)\;140\,\text{m},\; (ii)\;20\,\text{m west} (c) (i)  140 m,  (ii)  20 m east(i)\;140\,\text{m},\; (ii)\;20\,\text{m east} (d) (i)  140 m,  (ii)  60 m west(i)\;140\,\text{m},\; (ii)\;60\,\text{m west}
