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 have,

Distance towards east is represented by positive whereas distance towards west is represented by negative integer

It is given in the question that,

Distance travelled in the east direction = 20 km

Also,

Distance travelled in west direction = 30 km

Therefore,

Distance travelled from A = 20 + (-30)

= - 10 km

As the distance is negative, so we will represent the distance travelled by Rita from A towards the west direction
