Final answer:
To fill in the measurements every two hours over a 24-hour period, the measuring cup would be filled to 1 cup at 8:00 a.m., 2 cups at 10:00 a.m., 3 cups at 12:00 p.m., and so on until 9 cups at 10:00 p.m.
Step-by-step explanation:
To fill in the measurements every two hours over a 24-hour period, we can start by noting that the measuring cup was filled to the 3-cup mark by 6:00 a.m.
So, at 8:00 a.m., it would be 1 cup full. At 10:00 a.m., it would be 2 cups full. At 12:00 p.m., it would be 3 cups full. And so on until 6:00 p.m., where it would be 7 cups full.
At 8:00 p.m., it would be 8 cups full. Finally, at 10:00 p.m., it would be 9 cups full before starting the cycle again.
