If the difference of two numbers is 10 and their product is 17, what is the sum of their squares? Explain? A large water tank has two inlet pipes (a large one and a small one) and one outlet pipe. It takes 3 hours to fill the tank with the large inlet pipe. On the other hand, it takes 5 hours to fill the tank with the small inlet pipe. The outlet pipe allows the full tank to be emptied in 7 hours.

What fraction of the tank (initially empty) will be filled in 2.85 hours if all three pipes are in operation? Give your answer to two decimal places (e.g., 0.25, 0.75).
