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?
Answers
Step-by-step explanation:
Distance travelled towards east is represented with positive integer so it should be 20Km
As west is opposite to east so distance in the direction of west will be represented by negative integer so distance along west is −30Km
Final position will be net displacement =20+(−30)=−10Km, as it is negative so it shows that finally Rita is in west to its initial position.
Answer:
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
