Who is asking: Other
Level of the question: All
I need some assistance with the following:
Worker A can do a piece of work in 15 days, worker B in 12 days, and worker C in 10 days. Worker A works 2 days, worker B 3 days, and worker C 3 days. In what time can worker A and worker B finish the job by working together?
I think that the answer is 2 1/9 days.
This is a far as I got by trying to determine the answer:
Worker A 2/15
Worker B 3/12
Worker C 3/10
I added the fractions 240/1800 = 450/1800 + 540/1800 = 1230/1800
Now, I am unsure as to what to do next. Can someone provide me with some advice and assistance?
I thank you for any help that may be provided.
