Question

Prachi goes 20 km towards east from a point A and point B. From B, she moves 30 km
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?

Answer 1

Answer:

Here your answer !!

Step-by-step explanation:

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 prachi is in west to its initial position.

hope it has helped you!!
