Question

Kathryn's water bottle holds 20.25 ounces. Her doctor told her to drink half her body weight in ounces of water. Kathryn weighs 121.5 pounds. How many water bottles will she have to drink? (There is no convesion required from ounces to pounds)

Answer 1

Answer: She have to drink 3 bottles of water.

Explanation:

Given: Weight of Kathryn = 121.5 pounds

half of her weight =
`(121.5)/(2)=60.75\text{ pounds}`

So, she need to drink 60.75 pounds of water.

Kathryn's water bottle holds 20.25 ounces.

Number of water bottles she need to drink = (half of her weight) ÷ (Capacity of bottle)

`=(60.75)/(20.25)\\\\=(6075)/(2025)\\\\=3`

Hence, she have to drink 3 bottles of water.
