0 m/s
The question asks for the average velocity, not the average speed. Velocity is a vector quantity, meaning it has both magnitude and direction. Speed is a scalar quantity, only having magnitude.
Neha swims 100 meters in 1 minute. To calculate her average speed, we would divide the total distance by the total time: 100 meters / 60 seconds ≈ 1.67 m/s. However, the question asks for average velocity.
Since Neha starts and finishes at the same point, her displacement is zero. Average velocity is calculated as the total displacement divided by the total time. Therefore:
Average velocity = Total displacement / Total time = 0 meters / 60 seconds = 0 m/s
The correct answer is 0 m/s because her net displacement is zero.
