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).
