Dangelo Orr · Answer 1

Since 15 workers did 8 hours of work, the total amount of work needed is 120 hours. Half of this job would be 60 hours. Then divide this amount by the 5 workers doing the job. This would make the job 12 hours

Alison Lindsey · Answer 2

J=15w*8h=120 (worker*hours)

5h=120/2

5h=60

h=12 hours
