Q. kalau proyek perumahan akan selesai 25 hari oleh 8 pekerja, jika proyek tersebut dikerjkan oleh 16 orang, maka proyek selesai berapa hari?
Understand Relationship: Understand the relationship between the number of workers and the number of days to complete the project. This is an inverse relationship, meaning if the number of workers doubles, the time required should halve, assuming all workers work at the same rate.
Calculate Total Work: Calculate the total amount of work done by 8 workers in 25 days. This can be represented as work units, where 1 work unit is the amount of work one worker can do in one day. So, the total work is 8 workers ×25 days.Total work = 8 workers ×25 days = 200 work units.
Determine Completion Time: Determine how many days it would take for 16 workers to complete the same amount of work. Since 16 workers are twice as many as 8 workers, they should take half the time to complete the same amount of work if they work at the same rate.Days for 16 workers = 25 days /2=12.5 days.
