Explanation:
It is given that,
A bird flies 2 km to the south, then 0.2 km to the north. The displacement of the bird is equal to the shortest path covered by it.
Initially, the bird is moving in south direction and then it move to north. Displacement can be calculated using difference between initial position and final position.
d = 2.2 km - 0.2 km = 1.8 km
Hence, the displacement of the bird is 1.8 km
