Hector's school is holding a fitness challenge. Students are encouraged to exercise at least [tex]2 \frac{1}{2}[/tex] hours per week. Hector exercises about the same number of hours each week. During a 4-week period, he exercises for [tex]11 \frac{1}{2}[/tex] hours. Hector wants to compare his exercise rate with the fitness challenge rate.

How many hours per week does Hector exercise? [tex]\square[/tex] hour(s) per week

Answer :

Sure! Let's break down the problem step-by-step to find out how many hours per week Hector exercises.

First, we know that Hector exercises for a total of [tex]\( 11 \frac{1}{2} \)[/tex] hours over a 4-week period. To make it easier to work with, we'll convert this mixed number into an improper fraction or a decimal.

The mixed number [tex]\( 11 \frac{1}{2} \)[/tex] can be written as a decimal:
[tex]\[ 11 \frac{1}{2} = 11 + \frac{1}{2} = 11 + 0.5 = 11.5 \][/tex]

So, Hector exercises a total of 11.5 hours over 4 weeks.

Next, we need to find out how many hours he exercises per week. To do this, we'll divide the total number of hours by the number of weeks.

[tex]\[ \text{Hours per week} = \frac{\text{Total hours}}{\text{Number of weeks}} = \frac{11.5 \text{ hours}}{4 \text{ weeks}} \][/tex]

Now, let's perform the division:
[tex]\[ \frac{11.5}{4} = 2.875 \][/tex]

So, Hector exercises [tex]\( 2.875 \)[/tex] hours per week.

In conclusion, Hector exercises [tex]\( 2.875 \)[/tex] hours per week.
