The position of a runner in a race is a type of analog data. The runner’s position is tracked using sensors. Which of the following best describes how the position of the runner is represented digitally?
A
The position of the runner is determined by calculating the time difference between the start and the end of the race and making an estimation based on the runner’s average speed.
B
The position of the runner is measured and rounded to either 0 or 1 depending on whether the runner is closer to the starting line or closer to the finish line.
C
The position of the runner is predicted using a model based on performance data captured from previous races.
D
The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.

D. The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.

Explanation:

C was wrong for me :(

Introduction:

The runner position is detected by sensors in a race. It is very difficult to keep track of every racer position manually therefore computer program are used to keep exact recordings.

Explanation:

The data is sometimes recorded manually and is in analog form which is converted in to digital form.

Conclusion:

The correct answer is D. The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.
