Question:
Assume you have 20 workers, each has 100H health.
Each workers if does 1 time construction job, will consume 0.1H, but provide: (Health / 100)wp. (wp = working point)

Now，each House needs 2000wp to build, Well needs 2500wp, Plantation needs 2500wp and Foods Factory needs 3000wp.
If a worker stay in a House for an hour, his health will auto increase 5H(Max health is 100H).
Each House can stay maximum 16 workers in the same time.

Mission:

      。To build at least 1 House

      。To build at least 1 Well

      。To build at least 1 Plantation

      。To build at least 1 Foods Factory

      。After finish all buildings, restore all 20 workers health to 100H
How many hours you need to accomplish this mission? Feel free to post your answer and try to compare to others. Good luck!
Example:
- Send 20 workers to work 106 times, consume 10.6H but provide 100wp to build a House. Then 16 workers stay in a house for 3 hours to get back 100H. (means 3 hours is used)

p/s: Working time is instantly one. Mean no need wait, just resting in House need wait 1 hour.
