We know that

• She burns 18.5 calories per minute in routine 1.

,

• She burns 22 calories walking, and 16.3 calories per minutes running, in routine 2.

Based on the given information, we can express the following.


18.5t>22+16.3t

Now, we solve the inequality for t.-


\begin{gathered} 18.5t-16.3t>22 \\ 2.2t>22 \\ t>(22)/(2.2) \\ t>10 \end{gathered}

Therefore, Nicole has to run more than 10 minutes to burn more calories with routine 1.
