Quizplus · Accepted Answer

To find the total biking distance, add the two distances: $11 \frac{1}{2} + 6 \frac{4}{9}$. Convert to improper fractions: $11 \frac{1}{2} = \frac{23}{2}$ and $6 \frac{4}{9} = \frac{58}{9}$. Find a common denominator (18): $\frac{23}{2} = \frac{207}{18}$ and $\frac{58}{9} = \frac{116}{18}$. Add them: $\frac{207}{18} + \frac{116}{18} = \frac{323}{18}$. Simplify: $\frac{323}{18} = 17 \frac{17}{18}$.
