Workers at a library check the shelves to make sure that all books listed in the electronic catalog are accounted for. It takes an experienced worker 6 hours to check the shelves in a section of the library. It takes a newly hired worker 12 hours to check the same section of the library. How many hours would it take the two workers to check the shelves together in this section of the library?

Well considering it takes the experienced worker a total of 6 hours and the new worker a total of 12 it should be less than six.

If both work on the area they are familiar with it should only take about 4 to 5 hours but considering the new worker might not know where many things go or are supposed to be. It should take 5 hours.

If there were any answers for a multiple choice question this might've been easier.

I'm sticking with 4 hours and about 30 mins.

Hope I helped and a brainliest is always appreciated.
