How many days should it take theremaining 3 workers to build a barn?ExtraExtra: If a customer eeds to have a bam built in 7 days, what is the minimum number of workers that Amywould need to put on the job?

Answer 1

We have the next information

If with 5 works take 9 days to build a barn, then only one worker will take five times the time given(9 days), therefore if have that 1 worker will take 45 days to build a barn

then we divide 45 between 3 in order to know how many days will take to build a barn for 3 workers

`x=(45)/(3)=15`

to 3 workers will take 15 days to build a barn

If the customer needs to barn a build-in 7 days

`x=(45)/(7)=6.42=7`

we will need 7 workers to build a barn in 7 days
