Question

water flows through a pipe at a rate of 5 quarts per month. express this rate of flow in fluid ounces per hour. round your answer to the nearest hundredth.
*note: you must use these exact conversion factors to get this question right.

volume	time
1 pint (pt) = 2 cups (cups)	1 hour (hr) = 60 minutes (min)
1 quart (qt) = 2 pints (pt)	1 day (day) = 24 hours (hr)
1 gallon (gal) = 4 quarts (qt)	1 week (week) = 7 days (days)
1 cubic foot (ft³) = 7.481 gallons (gal)	1 month (month) = 30 days (days)
1 liter (l) = 1000 milliliters (ml)	1 year (year) = 365 days (days)
1 cubic meter (m³) = 1000 liters (l)
1 gallon (gal) = 3.785 liters (l)

Explanation:

Step1: Convert quarts to fluid ounces

Since 1 quart = 2 pints and 1 pint = 2 cups and 1 cup = 8 fluid ounces, then 1 quart = 2×2×8 = 32 fluid ounces. So 5 quarts = 5×32 = 160 fluid ounces.

Step2: Convert months to hours

Since 1 month = 30 days and 1 day = 24 hours, then 1 month = 30×24 = 720 hours.

Step3: Calculate the rate in fluid ounces per hour

The rate is the number of fluid ounces divided by the number of hours. So the rate is $\frac{160}{720}\approx0.22$ fluid ounces per hour.

Answer:

0.22
