Mark and Matthew signed out for a walk and 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 percent error round to the nearest 10th.
To calculate the percent error, we need to find the difference between the predicted time and the actual time.
The predicted time is 60 minutes, and the actual time is 53 minutes.
The difference is 60 - 53 = 7 minutes.
To find the percent error, we divide the difference by the predicted time and multiply by 100:
(7/60) * 100 ≈ 11.7
Therefore, the percent error is approximately 11.7% when rounded to the nearest 10th.
