Answer: About 150 minutes

Step-by-step explanation:

     We will set the function equal to 10,000, since that is the volume, and then solve for t.

     Given:

V(t)= 65t + 280

     Substitute:

10,000 = 65t + 280

     Subtract 280 from both sides of the equation:

9,720 = 65t

     Divide both sides of the equation by 65:

t ≈ 150 minutes
