$A$ man walks $30 \,m$ towards South. Then,turning to his right,he walks $30 \,m.$ Then,turning to his left,he walks $20 \,m.$ Again,he turns to his left and walks $30 \,m.$ How far is he from his initial position (in $m$)?

Radha moves towards South-East a distance of $7 \, km$,then she moves towards West and travels a distance of $14 \, km$. From here she moves towards North-West a distance of $7 \, km$ and finally she moves a distance of $4 \, km$ towards East. How far is she now from the starting point? (in $km$)

$A$ person travelled from a point $X$ straight to $Y$ at a distance of $80 \, m$. He turned right and walked $50 \, m$,then again turned right and walked $70 \, m$. Finally,he turned right and walked $50 \, m$. How far is he from the starting point? (in $m$)

Two buses start from the opposite points of a main road,$150 \, km$ apart. The first bus runs for $25 \, km$ and takes a right turn and then runs for $15 \, km$. It then turns left and runs for another $25 \, km$ and takes the direction back to reach the main road. In the meantime,due to a minor breakdown,the other bus has run only $35 \, km$ along the main road. What would be the distance between the two buses at this point? (in $km$)

$A$ square field $ABCD$ of side $90 \,m$ is so located that its diagonal $AC$ is from north to south and the corner $B$ is to the west of $D$. Rohan and Rahul start walking along the sides from $B$ and $C$ respectively in the clockwise and anticlockwise directions with speeds of $8 \,km/hr$ and $10 \,km/hr$. Where shall they cross each other the second time?

From the positions in the original figure,$C$ and $A$ move diagonally to opposite corners and then one side each clockwise and anticlockwise respectively. $B$ and $D$ move two sides each clockwise and anticlockwise respectively. Where is $A$ now?
