Final answer:
To find out how many glasses of water Addison drinks in one hour, we convert the amount she drinks within 2.75 hours to an hourly rate, yielding approximately 0.273 glasses per hour.
Step-by-step explanation:
To determine how many glasses of water Addison drinks in one hour, we need to convert the quantity to an hourly rate. Addison drinks 3/4 of an 8-ounce glass of water in 2 (3/4) hours, which is the same as 2.75 hours. To find out how much she drinks per hour, we can divide the amount she drinks in the given time period (3/4 glass) by the number of hours (2.75).
First, convert 3/4 of a glass to ounces: (3/4) × 8 ounces = 6 ounces.
Then, calculate the hourly rate: 6 ounces / 2.75 hours = 2.18 ounces per hour.
Finally, to express this as glasses per hour (considering one full glass is 8 ounces), we divide the ounces per hour by the number of ounces in a glass: 2.18 ounces per hour / 8 ounces per glass = 0.273 glasses per hour.
