Question

During 30 minute on the treadmil, la toya burned 20 calories per minute what is the function that represent this situation

Answer 1

Let c be the number of calories burned

and let t be the time taken to burn the calories.

At 1 minute, 20 calories are burned

Mathematically, we express that as;

`\begin{gathered} c=\text{ k}* t \\ \text{Where k is constant of proportionality;} \\ 20=k*1 \\ k=20 \end{gathered}`

Thus, the function that represents the situation is;

`\begin{gathered} \text{substitute the value of k in the equation above} \\ c=20t \end{gathered}`

ANSWER: The linear function that represents the situation is c=20t
