Mark and Matthew signed up to walk in a 5K Walk/Run Race. They predict it will take them 60 minutes to complete the race. Mark and Matthew finished the race in 53 minutes. What is the percentage error? Round to the nearest tenth.
The predicted time is 60 minutes and the actual time is 53 minutes.
To find the percentage error, we need to determine the difference between the predicted time and the actual time, and then divide it by the predicted time.
Difference = 60 - 53 = 7 minutes.
Percentage error = (Difference / Predicted time) * 100
= (7 / 60) * 100
= 11.67 (rounded to the nearest tenth).
Therefore, the percentage error is approximately 11.7%.
