There are several information's that are given in the question. Based on these information's the answer can be easily deduced.
Amount of water that <span>Mariana's swimming pool holds = 22000 gallons
7.5 gallons = 1 cubic feet
Then
22000 gallons = 22000/7.5 cubic feet
= 2933 cubic feet
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the second option or option "B".</span>

Answer:
The area of the speed-time graph gives us the distance travelled . In this case we drop a perpendicular from v=4 to t=2 . Hence, we get a rectangle and a triangle. Now we calculate the areas of the rectangle and the triangle. Rectangle = 2×4=8 m and triangle =1/2×(4–2)×4=4 m. Now to get the distance travelled we add the two up. Hence, distance travelled= (8+4)m =12 m.
