Mark and Mathew signed up to walk in a 5k walk/run race. They predict it will take them 60mjns to complete the race. Mark and Mathew finished the race in 53 mins. What is the percent error.
To find the percent error, we first need to calculate the absolute error, which is the difference between the predicted time and the actual time:
Absolute error = predicted time - actual time
Absolute error = 60 mins - 53 mins
Absolute error = 7 mins
Next, we can find the percent error by dividing the absolute error by the predicted time and multiplying by 100:
Percent error = (absolute error / predicted time) * 100
Percent error = (7 mins / 60 mins) * 100
Percent error = 11.67%
Therefore, the percent error is approximately 11.67%.
