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?


Answer :

We have,


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


It is given in the question that,


Distance traveled in the east direction = 20 km


Also,


Distance traveled 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.
