Question

Q.1 Sudha goes 30 km towards east from a point P to the point Q. From Q, she moves 50 km towards west along the same road. If the distance towards east is represented by a positive integer, how will you represent the distance travelled towards west? By which integer will you represent her final position from P?​

Answer 1

Answer:

she is 20 km far away from point P

Answer 2

Distance travelled towards east is represented with positive integer so it should be 20Km

As west is opposite to east so distance in the direction of west will be represented by negative integer so distance along west is −30Km

Final position will be net displacement =20+(−30)=−10Km, as it is negative so it shows that finally Sudha is in west to its initial position.
