The percent error is computed as follows:
[tex]\text{ Percent error = }\frac{|estimated\text{ value - actual value|}}{\text{actual value}}\cdot100[/tex]
The greatest percent error is obtained with an estimated value of 22.9 seconds. The actual value is 22.4 seconds, then:
[tex]\begin{gathered} \text{ Percent error = }\frac{|22.9-22.4|}{22.4}\cdot100 \\ \text{ Percent error = }\frac{0.5}{22.4}\cdot100 \\ \text{ Percent error = }2.2\text{ \%} \end{gathered}[/tex]
