Question

A man leaves his house at 7.30 am for a morning walk, and returns back at
8.15 am after covering 3 km. His displacement in this time is
(a) 2 km
(b) 0 km
(c) 8 km
(d) 4 km​

Answer 1

Explanation:

I think the answer is 4 kilometre

Answer 2

Answer:

(b) 0

Explanation:

• The displacement of him will be zero, despite the fact that the distance travelled will be non-zero because he will return to his starting point.
• Because distance is the whole path traversed, but displacement is the shortest distance between the initial and final positions, displacement can be zero but distance cannot be zero. At the end of a round, it may be zero.
