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?
NCERT Class 7th Mathematics Chapter 1 Integers



Rita moves to 20km east A to B and she moves 30 km to west so she move 10km towards west
A is the initial point,
It can be taken as 0
Rita moves towards east 20 km
It can be taken as +20
Rita moves towards west 30 km
It can be taken as -30
Distance between initial point and final point = 10 km towards west
It can be taken as -10
The final position of Rita is represented as -10
