ANSWER:
![16(1)/(3)=5(1)/(4)+5(2)/(3)+x](https://img.qammunity.org/2023/formulas/mathematics/college/o70tkl9hbv6v2gm0a05u8tf54absci04ap.png)
Explanation:
We have that there is a total time and a time for each week, the time for each week is equal to the total time, therefore the equation is the following
![16(1)/(3)=5(1)/(4)+5(2)/(3)+x](https://img.qammunity.org/2023/formulas/mathematics/college/o70tkl9hbv6v2gm0a05u8tf54absci04ap.png)
Therefore the correct equation is option A.
Now to calculate the value of x we must solve for x like this:
![\begin{gathered} x=16(1)/(3)-5(1)/(4)-5(2)/(3) \\ x=5(5)/(12) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/u7q5tf67vb4pgnm0uw5tgegftfgudtg02e.png)
Therefore the time of week 3 is 5 5/12 hours
