# 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 the distance travelled towards west? By which integer will you represent her final position from A?

We will represent the distance travelled towards west with negative integer.

Distance travelled towards east = $20\ km$

Distance travelled towards west = $30\ km$

Distance travelled from A = $[20+(-30)]\ km$

$-10\ km$

As the distance is negative, so final position of Rita from A is towards the west direction.
