Mia and Robert signed up to walk a 5K walk/race they predict it will take 60 minutes to complete the race via and Robert finished the race in 53 minutes. What is the percentage error?
To find the percentage error, we need to compare the predicted time to the actual time and calculate the difference.
Predicted time: 60 minutes
Actual time: 53 minutes
Difference: 60 - 53 = 7 minutes
To calculate the percentage error, we need to divide the difference by the predicted time and multiply by 100.
Percentage error = (difference / predicted time) * 100
Percentage error = (7 / 60) * 100
Percentage error ≈ 11.67%
Therefore, the percentage error is approximately 11.67%.
