Rita goes $20 k m$ towards east from a point A to the point B. From B, she moves $30 k m$ towards west along the same road. If the distance towards east is represented by a positive integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?

Solution

Distance travelled towards $e a s t$ is represented with a positive integer so it should be $20 k m$ .
As west is opposite to east so distance in the direction of $w e s t$ will be represented by $n e g a t i v e$ integer so distance along west is $- 30 k m$ .

The final position will be net displacement $= 20 + (- 30) = - 10 k m$ , as it is $n e g a t i v e$ so it shows that finally, Rita is in the west to its initial position.
