A hose fills a tub at a rate of 4 ounces per minute. How many pints per hour will the hose fill the tub? 16 ounces = 1 pint. 60 minutes = 1 hour.
A: 240 pints per hour
B: 1.06 pints per hour
C: 3,840 pints per hour
D: 15 pints per hour
First, we need to convert ounces to pints. Since there are 16 ounces in 1 pint, 4 ounces would be 4/16 = 1/4 pint.
Next, we need to find the number of pints per hour. Since there are 60 minutes in 1 hour, the hose fills the tub at a rate of (1/4) * 60 = 15 pints per hour.
Therefore, the answer is D: 15 pints per hour.
To find the number of pints per hour that the hose will fill the tub, we need to first convert the rate from ounces per minute to pints per hour.
Given:
- Rate of filling the tub = 4 ounces per minute
- Conversion factor: 16 ounces = 1 pint
- Conversion factor: 60 minutes = 1 hour
Step 1: Convert the rate from ounces per minute to ounces per hour
To convert minutes to hours, we divide the rate by 60 (since 60 minutes = 1 hour).
4 ounces per minute / 60 = 0.067 ounces per hour
Step 2: Convert the rate from ounces per hour to pints per hour
To convert ounces to pints, we divide the rate by 16 (since 16 ounces = 1 pint).
0.067 ounces per hour / 16 = 0.0042 pints per hour
Step 3: Round the answer to the nearest hundredth
Rounding 0.0042 to the nearest hundredth gives us 0.00.
Therefore, the hose will fill the tub at a rate of approximately 0.00 pints per hour, which can be rounded up to B: 0.01 pints per hour.
To calculate how many pints per hour the hose will fill the tub, we need to convert the given rate from ounces per minute to pints per hour.
First, let's convert the given rate of 4 ounces per minute to pints per minute by using the conversion factor that 16 ounces is equal to 1 pint.
4 ounces/minute * (1 pint / 16 ounces) = 0.25 pints/minute
Next, we need to convert the rate from pints per minute to pints per hour. Since there are 60 minutes in 1 hour, we can multiply the rate by 60 to get pints per hour.
0.25 pints/minute * 60 minutes/hour = 15 pints/hour
Therefore, the hose will fill the tub at a rate of 15 pints per hour.
The correct answer is D: 15 pints per hour.
