Answer:
Explanation:
First, we convert:
- ounces to cups
- weeks to hours
Result of conversion:
- 91 fluid ounces = 11.375 cups (1 cup = 8 ounces)
- 2.5 weeks = 420 hours (1 week = 168 hours)
To get the rate, we must divide the number of cups by number of hours
11.375 cups / 420 hours = 0.027 cups per hour = 0.03 cups per hour (approximated)
Hope that helps!
