Answer:
3 hours and 30 minutes
Explanation:
W = [tex]\frac{1}{9}t + \frac{1}{6}t\\\\[/tex]
1 = [tex]\frac{2}{18}t + \frac{3}{18}t[/tex]
1 = [tex]\frac{5}{18}t[/tex]
[tex]\frac{18}{5} = t[/tex]
3.6 → 60 decimal hours equals 36 minutes so the answer would be 3 hours and 30 minutes.
The chart I have attached shows decimal hours converted to hours. It helped me with this question.
