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 finish the race in 53 minutes. What is the percent error round to the nearest tent
To calculate the percent error, we need to find the difference between the predicted time and the actual time, and then divide that difference by the predicted time. The formula to calculate the percent error is:
Percent Error = (|Actual Value - Predicted Value| / Predicted Value) x 100
In this case, the predicted time was 60 minutes and the actual time was 53 minutes, so:
Percent Error = (|53 - 60| / 60) x 100
Percent Error = (|-7| / 60) x 100
Percent Error = (7 / 60) x 100
Percent Error ≈ 0.1167 x 100
Percent Error ≈ 11.67
Rounded to the nearest tenth, the percent error is approximately 11.7%.
