Question 8 O Mark this question 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 / f(t) di, which gives the total number of gallons of water that flowed through this pipe in 7 minutes. 4 3 2 Velocity (Gallons/Minute) O 2 5 6 7 X -1 Time (In Minutes)2 Velocity (Gallons/Min O 2 5 6 7 X -1 Time (In Minutes) o [ f(D) at = 15 gallons o [ f() at = 18 gallons O J F(D) dt = 17 gallons o [ f(t) at = 16 gallonsQuestion 22 O Mark this question While training for a marathon, Vera's velocity varied as shown on the graph below. Assume the horizontal axis shows the time in hours and the vertical axis shows the velocity in miles per hour.
