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)

Answer 1

To find the percent error, we first need to calculate the difference between the predicted time and the actual time:

60 minutes - 53 minutes = 7 minutes

Next, we need to calculate the percent error using the formula:

Percent Error = (|Predicted Value - Actual Value| / Predicted Value) * 100%

Plugging in the values:

Percent Error = (|60 - 53| / 60) * 100%
Percent Error = (7 / 60) * 100%
Percent Error = 0.1167 * 100%
Percent Error = 11.67%

Rounded to the nearest tenth, the percent error is 11.7%.
