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?

Answer 1

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%.
