A tank is leaking at an increasing rate as indicated by the data below. Use the table to answer the following questions.
\table[[Time (hr),0,1,2,3,4,5,6,7,8],[Leakage (
ga(l)/(h)r
,30,55,150,240,310,410,550,600,720]]
An upper limit estimate for the amount of material leaked after 4 hours is
◻
gal.
(Simplify your answer.)
A lower limit estimate for the amount of material leaked after 4 hours is
◻
gal.
(Simplify your answer.)
An upper limit estimate for the amount of material leaked after 8 hours is
◻
gal.
(Simplify your answer.)
A lower limit estimate for the amount of material leaked after 8 hours is
◻
gal. (Simplify your answer.)
If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 24,000 gallons of material, an estimate for the least amount of time for the tank to empty is
◻
hr.
(Round to the nearest tenth as needed.)
If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 24,000 gallons of material, an estimate for the most amount of time for the tank to empty is hr.
