How long will it take for a sink to fill if it empties in 4 minutes and fills in 3 minutes?
Fills in 3 minutes ===> gains 1/3 sink per minute. Empties in 4 minutes ===> loses 1/4 sink per minute. With faucet and drain open simultaneously, gain is [ (1/3) minus (1/4) ] sink per minute = (4/12) - (3/12) = 1/12 sink per minute. Time to gain 1 whole sink = 1/(1/12) = 12 minutes to fill.

How long will it take a tank to be be filled by one pipe in 9 minutes and drained by another pipe in 12 minutes?
We're guessing that the question is trying to ask:If one pipe can fill the tank in 9 minutes, and another pipecan empty the tank in 12 minutes, how long does it take thetank to fill if both pipes are open ?So that's the question we'll go ahead and answer.The first pipe fills 1/9th of the tank every minute.The second pipe empties 1/12th of the tank every minute.When they're both open, (1/9 - 1/12) of the tank fills every minute.(1/9) - (1/12) = (4/36) - (3/36) = 1/36Since 1/36th of the tank fills every minute, it takes 36 minutes to fill.
A pool can be filled by one pipe in 7 hours and by a second pipe in 2 hours How long will it take using both pipes to fill the pool?
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
If it takes 12 minutes to fill 200 bottles of soda at this rate how many minutes will it taKE the machine to fill 500 bottles of soda?
To find out how long it takes to fill 500 bottles, first determine the rate of filling. If 200 bottles take 12 minutes, then the rate is ( \frac{12 \text{ minutes}}{200 \text{ bottles}} = 0.06 ) minutes per bottle. For 500 bottles, it would take ( 500 \times 0.06 ) minutes, which equals 30 minutes. Thus, it will take 30 minutes to fill 500 bottles of soda.
Jim can fill a pool carrying buckets of water in 30 minutes sue can do the same job in 45 minutes tony can all three fill the pool together?
Since you didn't write the Tony's time, let find for how long Jim and Sue can fill the pool together. Jim can fill 1/2 of the pool in 15 minutes. Sue can fill 1/3 of the pool in 15 minutes. Together can fill 5/6 of the pool in 15 minutes (1/2 + 1/3). In how many minutes (let's say x minutes) they will fill 1/6 of the pool? Since it is left a small piece of the pool to fill out, it will take a few minutes to fill it. So we can form a proportion such as: (5/6)/(1/6) = 15/x 5/1 = 15/x cross multiply 5x = 15 divide both sides by 5 x = 3 It will take 3 minutes to fill 1/6 of the pool. So that together they will fill the pool in 18 minutes (15 + 3).
If you have a 6000 liter tank it takes one pipe to fill it in 50 minutes and the other pipe in 75 minutes how long will it take both pipes at the same time?
It would take the too pipes 30 minutes to fill the tank when working together.This figure can be found in the following manner:Find the fill-speed of the first pipe50 minutes to fill 6000 Liters. 6000L/50m gives us 120L/m (liters-per-minute)6000 Liters in 75 minutes = 6000L/75m = 80L/mNext find the speed of the second pipeNow we combine the two rates (120+80), and we find that the pipes have a combined fill-speed of 200L/mFinally, we determine that it takes 30 minutes to fill the tank at 200L/m

If it takes chis 30 minutes to fill the pool and Sarah 45 minutes to fill the pool and Billy 90 minutes to fill the pool how long will it take all 3 to fill the pool?
chis fills (1/30) of the pool every minute.Sarah fills (1/45) of the pool every minute.Billy fills (1/90) of the pool every minute.Working together, they fill [ (1/30) + (1/45) + (1/90) ] every minute.(1/30) + (1/45) + (1/90) = (3/90) + (2/90) + (1/90) = (6/90) = 1/15Together, they fill (1/15th) every minute, so it takes 15 minutes to fill it completely.
One pump can fill a pool in ten minutes another can fill the pool in 15 minutes how long to fill the pool if both pumps are running?
The first pump fills (1/10th) of the pool in 1 minute.The second pump fills (1/15th) of the pool in 1 minute.With both running, they fill(1/10 + 1/15) = (3/30 + 2/30) = 5/30 = 1/6th of the pool in 1 minute.They have to run for [ 1 / (1/6) ]= 6 minutes in order to fill the pool.

If it takes 45mins to fill a bucket with water from hose 1 and it takes 30mins to fill another bucket from hose 2 How long would it take to fill a bucket using hose 1 and 2 at the same time?
Assuming the buckets are identical... Hose 1 fills 1/45 per minute and hose 2 fills 1/30 per minute, so together in one minute they would fill 1/45 + 1/30 ie 5/90 or 1/18, ie the bucket would be filled in 18 minutes.
