# 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?

**Solution:**

Distance travelled by Rita towards east = 20 km (distance travelled towards the east is represented by a positive integer)

Distance travelled by Rita towards west = -30 km (distance travelled towards the west is represented by a negative integer)

Final position of Rita from A = [20 + (-30)] km

= (20 - 30) km

= -10 km

Therefore, we will represent her final position from A by a negative integer, that is, -10
