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
To find the percent error, we need to calculate the difference between the predicted time and the actual time, and then divide that difference by the predicted time and multiply by 100.
Predicted time: 60 minutes
Actual time: 53 minutes
Difference = Predicted time - Actual time = 60 - 53 = 7 minutes
Percent error = (Difference / Predicted time) * 100
= (7 / 60) * 100
= 11.7
Rounded to the nearest tenth, the percent error is 11.7%.
