The Ultimate Riddle*************
    #1525400 - 05/06/03 08:25 PM (15 years, 17 days ago)

Working alone, Mary can complete a certain job in 8h. If Mary and Paul work together they can complete the same job in 6h. If Peter and Paul work together, they can complete the same job in 10h. How long would it take for Peter, Paul and Mary working together to complete the job?

3151351847943843581383489797.131381^18 hours because u fail to take into account that peter is an illiteate redneck and that paul is trippin way too hard.

9 hours and 20 minutes.

Mary does the job in 8h. Paul does the job in 4h. Peter does the job in 16 hours.

mary does it in 8
paul shortens it by 2,
but Peter lengthens it by 2.
so 8+2-2=8.
maybe?

4.43 but i think i messed something up
the job = 1
one hour of marys work is 1/8
mary and paul can do it in 6 hours SO
6/8 + 6/x =1
common denominator is 8x the cancel out
6x + 48 = 8x
Paul can do it in 24 hours
paul and peter together = 10 hours
10/24 + 10/x = 1
peter can do it in ROUGHLY (this is where i think i missed something) 17 hours
Peter Paul and mary togetethr = 1
x/8 + x/24 + x/17 = 1
Common denominator is 408 and then cancel out
51x +17x +24x = 408
92x = 408
Its Takes Peter Paul and Mary roughly 4.43 hours to complete the task
Its probably wrong

Mary works at a rate of 1/8 of the job per hour.
Paul works ata rate of 1/24 of the job per hour.
Peter works at a rate of 7/120 of the job per hour.

Using a common denominator of 240 and a little more math, it would take them 4.44 hours.

You were right Vader!

I thought the ultimate riddle was the sound of one hand clapping.....


--------------------
After one comes, through contact with it's administrators, no longer to cherish greatly the law as a remedy in abuses, then the bottle becomes a sovereign means of direct action.  If you cannot throw it at least you can always drink out of it.  - Ernest Hemingway

If it is life that you feel you are missing I can tell you where to find it.  In the law courts, in business, in government.  There is nothing occurring in the streets. Nothing but a dumbshow composed of the helpless and the impotent.    -Cormac MacCarthy

He who learns must suffer. And even in our sleep pain that cannot forget falls drop by drop upon the heart, and in our own despair, against our will, comes wisdom to us by the awful grace of God.  - Aeschylus
