Shown below is the graph of the flow rate f(t) of a pipe, in gallons per minute. Here, t = the number of minutes. Using this information, find S f(t) dt, which gives the total number of gallons of water that flowed through this pipe in 7 minutes. Velocity (Gallons/Minute) 1 2 3 4 5 6 Time (In Minutes) S'F(1) dt = dt = 24 gallons 'f(t) dt=25 f(t) dt = 25 gallons SF(t) dt = f(t) dt =26 gallons
