To calculate the percent error, we use the formula:
Percent Error = |(Predicted Time - Actual Time) / Predicted Time| * 100
Plugging in the values:
Predicted Time = 60 minutes
Actual Time = 53 minutes
Percent Error = |(60 - 53) / 60| * 100
Percent Error = |7 / 60| * 100
Percent Error = 0.1167 * 100
Percent Error = 11.7%
Therefore, the percent error is 11.7%.
