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

Answer 1

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%.
