Approximately 9.5% of the racers did not complete the marathon.

Solución

To determine the percentage of racers who did not complete the marathon, follow these steps:
  1. Total Racers Started: 210
  2. Racers Who Completed: 190
  3. Racers Who Did Not Complete: 210 - 190 = 20
  4. Calculate the Percentage:
  5. Round to One Decimal Place:
Answer: Approximately 9.5 % of the racers did not complete the marathon.

Bonus Knowledge

To find the percentage of racers who did not complete the marathon, we first determine the number of racers who did not finish. This includes those who gave up and those who were disqualified.
Total racers who did not complete = 13 (gave up) + 7 (disqualified) = 20.
Now, we will calculate the percentage of racers who did not complete the marathon out of the total number of racers that started:
Percentage = (Number of non-finishers / Total number of racers) × 100
Percentage = (20 / 210) × 100 ≈ 9.5%.
So, approximately 9.5% of the racers did not complete the marathon.
