The question is 'Using my tap, it takes 6 minutes to fill our water tank. Using my neightbour's hose, it takes 9 minutes. How long would it take if I used both the tap and the hose?'
Can you guys please answer it and tell me how you got the answer? Thanks. |

| The answer is: You ought to be doing your own homework and not asking members of a photography site to do it for you. :P |

| Geez, that water tank will be overflowing long before the answer is ever posted. |

Does the tap lead from the water tank? In that case you're screwed.

Answer it? -- no. (not that it matters, most textbooks have the answer in the back).
But, tell you have to figure it out? -- sure. But what level of math do you want that explaination at?
BTW: drawing a picture helps when problems are not making any sense. Working out what picture to draw works out the problem.

Assume the tank holds 36 gallons (a number divisible by both 6 and 9)
Then the tap flows at 6 gals per minute and the hose at 4 gallons per minute.
Both of them together flow at 10 gals per minute.
How long to fill the 36 gallon tank at 10 gals per minute? That's your answer, I believe. That's how I'd tackle it anyway, but it's been over 40 years since I had to "do maths" :-)

Hah, I hadn't realized John had already answered :-) At least I listed a problem-solving approach, which proves I thought it out on my own :-) Whoo, I feel validated!

That's one way to solve it but i bet this kid is in a math class that wants it solved differently.. lol

6/2 = x
9/2 = y
your answer would be x + y; which is 7.5 minutes theoritically
edit: but I doubt your neighbour will allow you to use his hose, so a real-life answer would still be 6 minutes. Also due to inconsistency of water supplies in the neighbourhood, there should be a tolerance of about 5% to the total time.
UPDATE: as stated by Bear, this is wrong... damn... I need more coke

Oh, no doubt... So what would be the "correct" problem-solving approach? 6x + 9y = z etc etc? I can't quite remember how to do all that ;-)

Huh? First, according to the problem the tap is faster than the hose, and second, your answer says it takes longer to fill with both than it does with the tap alone...

It can't take longer to fill the same tank than 6 minutes if the tap can do it in 6 minutes. Because you are using the tap and hose. I believe you left a step out of the equation. UNLESS it's a trick question and he his hooking the hose on his tap!

You forgot to count in the amount of time it takes to drag your neighbor's hose into your house and up to your sink. Assuming you have to club your neighbor seven times with the heel of Daddy's boot to render him a non-combatant it should take about two minutes right there.
As you dig through his garage and uncover the hose, you are probably going to spend another 3.5 minutes.
At this point your neighbors wife will arrive and call the police. You have about three minutes, based on past experience, before they arrive. Given the one minute it takes to drag the hose, you only really have about two spare minutes before you go back to the slammer.
Do you think you can fill the tank that fast?

I guess the answer would still be 6 minutes.
tell your teacher that your neighbour wont let you use his water supply because he knows your tap can do the job. |

The answer: never
You neighbor, sick and tired of your shenanigans, will beat you into unconciousness when he sees you taking his hose. |

This being a photo site and all, we'll be expecting a picture of one or more of the following:
- A full water tank
- Your neighbor's hose
- Your neighbors unconscious body lying in the garage
- Your Math teacher giving the thumbs-up
** extra credit for a really cool water drop / splash shot in the tank |
