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

## Step 1<br />The problem is asking us to identify the best method for digitally representing the position of a runner in a race. The position of the runner is a type of analog data, which means it can take any value within a range. <br /><br />## Step 2<br />Let's evaluate each option:<br /><br />### Option A<br />This option suggests calculating the time difference between the start and end of the race and making an estimation based on the runner's average speed. This method does not accurately represent the position of the runner as it does not account for the runner's speed at different points in time.<br /><br />### Option B<br />This option suggests measuring the position of the runner and rounding it to either 0 or 1 depending on whether the runner is closer to the starting line or closer to the finish line. This method is not accurate as it does not account for the runner's position in between these two points.<br /><br />### Option C<br />This option suggests predicting the position of the runner using a model based on performance data captured from previous races. This method is not accurate as it does not account for the runner's speed at different points in time.<br /><br />### Option D<br />This option suggests sampling the position of the runner at regular intervals to approximate the real-world position, and using a sequence of bits to represent each sample. This method is accurate as it accounts for the runner's speed at different points in time and uses a sequence of bits to represent each sample.
