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.
[tex]18.5t>22+16.3t[/tex]Now, we solve the inequality for t.-
[tex]\begin{gathered} 18.5t-16.3t>22 \\ 2.2t>22 \\ t>\frac{22}{2.2} \\ t>10 \end{gathered}[/tex]
