Answer:
There are 9 days between each pickup.
Step-by-step explanation:
Since in each trip barrels picked up by the recycling facility = 96
and each barrel holds the wastewater = 30 quarts
So total quantity of wastewater = 30×96 = 2880 quarts
Rate of filling each barrel is = 13 quarts per hour
So time to fill 2880 quarts = hours
Now we can convert 221.54 hours = days
= 9.23 days
Therefore, there are 9 days between each pickup.
