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
represent the distance travelled towards west? By which integer will
you represent her final position from A?

Answers
since the distance towards East is represented by a positive reply integer , the distance travelled towards west will be represent by a negative integer.
Distance travelled in East direction = 20 km.
Distance travelled in West direction = - 30 km.
Distance travelled from A = 20 + (-30) km
= 20 -30 km
= - 10 km.
Therefore , we will represent the distance travelled by Rita from point A by a negative integer , i.e, -10 km ( i.e, Rita is now as west direction).
Answer:
-10km
Step-by-step explanation:
From the question, it is given that
A positive integer represents the distance towards the east.
Then, distance travelled towards the west will be represented by a negative integer.
Rita travels a distance in east direction = 20 km
Rita travels a distance in west direction = – 30 km
∴Distance travelled from A = 20 + (- 30)
= 20 – 30
= -10 km
Hence, we will represent the distance travelled by Rita from point A by a negative integer, i.e. – 10 km
