Answer 1

Answer:

That is 6 days are between each pickup

Step-by-step explanation:

The recycling facility picks up 120 full barrels on each trip, and each barrel holds 12 quarts of wastewater.

Volume of water carried by recycling facility = 12 x 120 = 1440 quarts.

Wastewater is filling barrels at the rate of 11 quarts per hour.

Number of hours required to fill 1440 quarts $=\frac{1440}{11}=130.91\texttt{ hours}$

Number of days$=\frac{130.91}{24}=5.45\texttt{ days}$

So, 5.45 days are between each pickup

That is 6 days are between each pickup

Answer 2

11t=120(12)

11t=1440

t=1440/11

However t is in hours and we want to know days so:

d=(1440/11)/24

d=1440/264

d=60/11

d=5 5/11 days
