B is the initial point,
It can be taken as 0.
Neetu goes towards east 35km
It can be taken as +35.
Neetu moves towards west 45km
It can be taken as -45.
Distance between initial point and final point = 10 km towards west
It can be taken as -10.
So the final position of Neetu is represented by an integer -10.
