Question 964695: All members of a crew work at the same pace. If only 4 members of the crew are working, they complete the job in 18 days. How many hours will it take all 9 members of the crew to complete the same job?
You can put this solution on YOUR website! The rate of working for members is:
[ 1 job ] / ( 18 days ]
--------------------------- member will take times as long
to finish the job, so the rate for member is:
[ 1 job ] / [ 72 days ]
----------------------
The rate for members would be times
as fast as the rate for member, so the rate is: , or
[ 1 job ] / [ 8 hrs ]
All 9 members of the crew take 8 hrs
to complete the same job
