Question

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.

Answer 1

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%.
