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 percent error? Round to the nearest tenth. (1 point) Responses 11.7% 11.7% 13.2% 13.2% 15.4% 15.4% 17.5%
To find the percent error, we can use the formula:
Percent error = ((Observed value - Predicted value) / Predicted value) * 100
In this case, the observed value is 53 minutes, and the predicted value is 60 minutes.
Percent error = ((53 - 60) / 60) * 100
Percent error = (-7 / 60) * 100
Percent error = -11.7%
Therefore, the percent error is 11.7%.
