To determine how much time Brianna has for each section, you can divide the total time she has by the number of sections.
Brianna has \(\frac{5}{6}\) of an hour, and there are 3 sections.
To find the time for each section, divide \(\frac{5}{6}\) by 3:
\[ \text{Time for each section} = \frac{5}{6} \div 3 = \frac{5}{6} \times \frac{1}{3} = \frac{5 \times 1}{6 \times 3} = \frac{5}{18} \text{ hours} \]
Now, to convert this into minutes, we can multiply by 60 minutes per hour:
\[ \frac{5}{18} \times 60 = \frac{300}{18} = \frac{50}{3} \approx 16.67 \text{ minutes} \]
Thus, Brianna has approximately \(16.67\) minutes, or \(16\) minutes and \(40\) seconds, to spend on each section.
