Question

A runner starts at point A, runs around a 1-mile track and finishes the run back at point A. Which of the following statements is true?

A. The runner's displacement is 1 mile.
B. The runner's displacement is zero.
C. The distance the runner covered is zero.
D. The runner's speed was zero.

Answer 1

The runners displacement is zero

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

When an object moves from initial point A to final point B is known as displacement.

Thus, when a runner starts from initial point A and then after running for 1 mile it reaches to the same point A this means that displacement of the runner is zero.

Thus, we can conclude that out of the given options, the statement runner's displacement is zero is true.
