Final answer:
To find the greatest percent error among the predictions, calculate the percent error for each prediction by comparing it to the actual winning time. Then, determine the greatest percent error.
Step-by-step explanation:
To find the greatest percent error among the predictions, we need to compare each prediction to the actual winning time and calculate the percent error for each one. The percent error can be calculated using the formula:
Percent Error = |(Predicted Time - Actual Time)| / Actual Time * 100
After calculating the percent error for each prediction, we can determine the greatest percent error among them.
