Q.6 Rita goes 20 km towards east from a point A to the 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 her final position from A?

Distances travelled towards east from point A will be represented by positive integer i.e. +20 km.

Distance travelled towards the west from point B will be represented by negative integer, i.e., —30 km.

Final position of Rita from A

= 20 km – 30 km = – 10 km

Hence, the required position of Rita will be presented by a negative number, i.e., -10.
