A large water tank has two inlet pipes (a

large one and a small one) and one outlet

pipe. It takes 2 hours to fill the tank

with the large inlet pipe. On the other

hand, it takes 6 hours to fill the tank

with the small inlet pipe. The outlet

pipe allows the full tank to be emptied

in 8 hours.

What fraction of the tank (initially

empty) will be filled in 1.85 hours if

all three pipes are in operation? Give

your answer to two decimal places (e.g.,

0.25, 0.5, or 0.75).

It should be full (1.00) and some had already been spilled.
