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 need to calculate the difference between the predicted time and the actual time, and then divide that difference by the predicted time. Finally, we multiply the result by 100 to express it as a percentage.

Actual time: 53 minutes
Predicted time: 60 minutes

Difference = Predicted time - Actual time
Difference = 60 - 53
Difference = 7

Percent error = (Difference / Predicted time) * 100
Percent error = (7 / 60) * 100
Percent error = 0.11666666666666667 * 100
Percent error ≈ 11.7

So, the percent error is approximately 11.7%.
