My mom signed up to run a 5k race. She predicted it would take her 60 minutes to complete it but she completed it in 53 minutes? what is the percent error? round to nearest tenth
To calculate the percent error, we can use the following formula:
Percent Error = (Actual Value - Predicted Value) / Predicted Value * 100%
In this case:
Actual Value = 53 minutes
Predicted Value = 60 minutes
Percent Error = (53 - 60) / 60 * 100%
Percent Error = -7 / 60 * 100%
Percent Error = -0.11666666666666667 * 100%
Rounded to the nearest tenth, the percent error is approximately -11.7%.
