To find out how many hours per week Hector exercises, we need to divide the total number of hours he exercises over the 4-week period by the number of weeks.
Hector exercises for a total of 11 1/2 hours over 4 weeks.
First, convert 11 1/2 hours to an improper fraction for easier calculations:
11 1/2 hours = 11 + 0.5 = 11.5 hours.
Now, divide this total by the 4 weeks:
\[ \text{Hours per week} = \frac{11.5 \text{ hours}}{4 \text{ weeks}} = 2.875 \text{ hours per week} \]
Now, convert 2.875 to a fraction.
2.875 can be expressed as:
2.875 = 2 + 0.875 = 2 + \frac{7}{8} = \frac{16}{8} + \frac{7}{8} = \frac{23}{8}
So, Hector exercises approximately \( 2.875 \) hours per week, or \( \frac{23}{8} \) hours.
Therefore, Hector exercises approximately:
2.875 hour(s) per week or \(\frac{23}{8}\) hour(s) per week.
