Answer:
9 seconds
Explanation:
From Jenny's swim graph
• Jenny burned 100 calories in 15 minutes.
To determine how long it will take her to burn off a -calorie smoothie that she had for breakfast, we find the unit rate in Minutes per calorie.
[tex]\begin{gathered} Unit\text{ Rate=}\frac{15\text{ minutes}}{100\text{ Calories}} \\ =0.15\text{ minutes per Calorie} \\ =0.15\times60\text{ seconds per Calorie} \\ =9\text{ seconds per Calorie} \end{gathered}[/tex]
Therefore, Jenny will burn a-calorie smoothie in 9 seconds.
