A hiker rides $700\, m$ north, $300$ meast, $400 \,m$ north $600\, m$ west, $1200\, m$ south, $300\, m$ east and finally $100\, m$ north. Draw the path of motion of the biker. What distance did he cover ? What was his displacement ?

$(ii)$ Distance travelled by the biker
$= OA + AB + BC + CD + DE+ EF + FO$
$=700 m +300 m +400 m+600 m +1200 m +300 m +100 m$
$=3600 \,m$
$(iii)$ Displacement of biker $=0$ (zero).
