We can first find how much ounces it is filled per second:
72×0.58
=41.76ounces

We can then find how long it will take by dividing 11,000 by the abswer we found above:
11,000÷41.76
=263.4099...
≈263.41ounces

Therefore,the answer is 263.41 ounces.

Please also note that this question belongs to the mathematics category!

Hope it helps!

Answer: 263.4 sec

Explanation:

Ounces of water in 1 second =
Density* rate=0.58ounces/inch^3* 72inch^3/sec=41.76ounces/ sec

This means that 41.76 ounces of water is getting collected in tub in 1 second

Then 11000 ounces of water will be collected in=
(1)/(41.76)* 11000=263.40seconds

The time taken to fill the tank upto 11000 ounces will 263.40 seconds.
