Answer 2

Answer:

                <----------190km (west)

A-------------C----------------------> B    

---------240km (east)--------->

Since the distance towards east is represented by a  +ve integer, the distance towards west can be represented as a  -ve integer.

Rita travelled 240km towards east from A to reach B, then she travelled along the same road toward west(opposite direction) for 190km to reach C.

Since we represent distance towards east as +ve and distance towards west as -ve, the final position C from A is,

240 - 190 = 50

the final position from A is +50 km (towards east)
