Answer:
[tex]\boxed{\text{10.0 lb/wk}}[/tex]
Step-by-step explanation:
1. Calculate the number of days
1 week = 7 da
2. Convert days to hours
24 h = 1 da
[tex]\text{No. of hours}= \text{7 da} \times \dfrac{\text{24 h}}{\text{1 da}} = \text{168 h}[/tex]
3. Convert hours to ounces
1h = 0.952 oz
[tex]\text{No. of ounces} = \text{168 h} \times \dfrac{\text{0.952 oz}}{\text{1 h}} = \text{159.9 oz}[/tex]
4. Convert ounces to pounds
1 lb = 16 oz
[tex]\text{No. of hours}= \text{7 da} \times \dfrac{\text{24 h}}{\text{1 da}} = \text{168 h}[/tex]}
[tex]\text{ The biggest loser lost }\boxed{\textbf{10.0 lb/wk}}[/tex]
