For Nick, we have the following information:
[tex]\begin{gathered} x=10.8,\mu=11.4,\sigma=0.4 \\ \Rightarrow z=\frac{x-\mu}{\sigma}=\frac{10.8-11.4}{0.4}=-1.5 \end{gathered}[/tex]
For Ryan, we have the following:
[tex]\begin{gathered} x=11.2,\mu=11.5,\sigma=0.1 \\ \Rightarrow z=\frac{11.2-11.5}{0.1}=-3 \end{gathered}[/tex]
Notice that the z score for Ryan is greater than the z score for Nick, this means that the speed for Ryan is greater compared to his team. Therefore, the correct option is Ryan
