large fills 1/9 per hour, large and small fill 1/6 per hour so small fills 1/6 - 1/9 per hour, ie 1/18, so small alone would take 18 hours.

Pipe A fills 1/12 of the tank per hour, and Pipe B fills 1/8 of the tank per hour. Together, they fill 1/12+1/8 of the tank per hour. 1/12+1/8=(1*8)/(12*8)+(1*12)/(12*8)=(8+12)/(12*8)=20/96=5/24 of the tank per hour So, it would take 1/(5/24)=24/5 = 4.8 hours to fill the tank with both pipes.

In one hour first pipe fills 1/7th of pool, other pipe fills one-half, so together in one hour they fill 1/7 + 1/2 ie 9/14 so would take 14/9 hours (93 and a third minutes) to fill the pool. ie 1 hr 33 min 20 sec

Hose A fills 1/3 of the pool per hour, hose B fills 1/4 of the pool per hour, and hose C fills 1/12 of the pool per hour. Conveniently, these easily convey to 4/12, 3/12, and 1/12. So all three hoses together fill 4/12 + 3/12 + 1/12 = 8/12 (or 2/3) or of the pool per hour. Therefore it takes one and one-half hours to fill the pool all the way. At the end of hour 1 the pool will be 2/3 of the way full, and since there's only 1/3 of the pool left to fill and our hoses can fill 2/3 of it per hour, we only need to run them for half-an-hour to get the last 1/3.

The inlet valve fills 1/6th of the vat in an hour.The outlet valve drains 1/10th of the vat in an hour.When they are both open, (1/6th - 1/10th) of the vat fills in an hour.(1/6 - 1/10) = (5/30 - 3/30) = 2/30 = 1/15th fills in one hour.So with both valves open, it takes 15 hours to fill the vat.

Pool capacity in gallons divided by fill time in hours equals fill rate in gallons per hour (gal / hr = gal/hr).

1.5 hours if the rate of flow is constant.

Depends on water pressure and how many hoses you use. Overnight

1.5 hours

Assuming the flow rate is constant (in a real system, this probably will not be the case, at least for the drain; it probably drains faster when nearly full than when nearly empty), then for convenience sake let's say the pool holds six units of water. It fills at 2 units per hour and drains at 1 unit per hour. If both pipes are open, the net gain is 1 unit per hour, so it will fill in six hours (and then start overflowing unless both pipes are shut off).
