There are 7 days in a week right? so ----> 1 week = 7 days
Now, just convert days per week into hours so ----> 7 days × 24 hours = 168 hours
168 hours converted to ounce are around 160 ounces =, or 159.9 oz to be more precise. (we convert hours to ounces so we can then find out the answer in pounds)
Lastly, convert the ounces you got into pounds so ----> 10 lbs per week
