All the members of a construction crew work at the same pace. six of them working together are able to pour foundation in 22 hours. how many hours would this job take if the number of workers increased by factor of 2?

if possible show work

11 hours.

Step-by-step explanation:

We have, 22 hours required to pour foundation when 6 of them working together.

If the number of workers increased by a factor of 2 i.e. (2 × 6) = 12 workers work together then we have to find the time required to do the same work.

So, we will use the unitary method to calculate the time.

22 hours required for the job when 6 of them working together.

So, 12 workers together can do the same job in hours. {Since more the number of workers less will be the time required. (Answer)
