ANSWER:
From the question, it is given that:
A positive integer represents the distance towards the east.
Then, distance traveled 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 traveled by Rita from point A by a Negative Integer, i.e. – 10 km
Answer:
14kilometre
