A swimming pool is being filled at the rate of 54 pt/min (pints per minute). How many quarts per hour is this?
Rainbow [258]

Answer:

Approximately 1620\; \text{quart} / \text{hour}.

Step-by-step explanation:

The given quantity was in the unit \displaystyle \frac{\text{pint}}{\text{minute}} while the required quantity should have the unit \displaystyle \frac{\text{quart}}{\text{hour}}. It would thus be necessary to use conversion factors of the following forms:

\begin{aligned}\frac{\text{pint}}{\text{minute}} \times \underbrace{\frac{\text{minute}}{\text{hour}} \times \frac{\text{quart}}{\text{pint}}}_{\text{conversion factors}} &= \frac{\text{quart}}{\text{hour}}  \end{aligned}.

Make use of the fact that:

  • 1\; \text{pint} = 0.5\; \text{quart}, and
  • 60\; \text{minute} = 1\; \text{hour}.

Rearrange the equation 1\; \text{pint} = 0.5\; \text{quart} to obtain the conversion factor:

\begin{aligned} 1 &= \frac{0.5\; \text{quart}}{1\; \text{pint}}\end{aligned}.

Similarly, rearrange the equation 60\; \text{minute} = 1\; \text{hour} to obtain the conversion factor:

\begin{aligned} 1 &= \frac{1\; \text{hour}}{60\; \text{minute}}\end{aligned}.

Combine both conversion factors and evaluate:

\begin{aligned} & 54\; \frac{\text{pint}}{\text{minute}} \\ =\; & 54\; \frac{\text{pint}}{\text{minute}} \times \frac{0.5\; \text{quart}}{1\; \text{pint}} \times \frac{60\; \text{minute}}{1\; \text{hour}} \\ =\; & (54 \times 0.5 \times 60) \; \frac{\text{pint} \times \text{quart} \times \text{minute}}{\text{minute} \times \text{pint} \times \text{hour}} \\=\; & 1620\; \frac{\text{quart}}{\text{hour}}\end{aligned}.

Nikolay [14]
So you're adding up .1, .002, and .000 003.
0.1 + 0.002 + 0.000003 = 0.102 003, or B.
