# Math Help - Word Problem work

1. ## Word Problem work

Two Workers do a job in 12 hours working together

One worker does half then other one does other half they finish in 25 days

how long will it take each alone?

I need thins really fast if someone can give me equations i can solve but i am only able to get 1st one

$(1/12)x+(1/12)y=1$

$(1/12)x+(1/12)y=1$
I think you means 12 days not hours.

Let $x$ be the time it takes the first worker. Let $y$ be the time it takes the second worker. When working together we have $\frac{12}{x}+\frac{12}{y} = 1$. When the first worker does half the full job in $x$ days so it takes him $x/2$ days to do half-the job. Likewise it does the other worker $y/2$ days. So $x/2+y/2 = 25$. Now solve these equations.

3. thank you solving them now

Hmmm i got it solutions are 20 and 30

4. I got that too.
