Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
If it takes 10 people 10 days to shovel 10,000 pounds of coal, how many days will it take half of these ten people to shovel 40,000 pounds of coal?

### Response:
 Watu 10 wanachimba paundi 1000 ya makaa ya mawe kwa siku kwa sababu 10,000 / 10 = <<10000/10=1000>>1000
Nusu ya watu hawa ni 10/2= <<10/2=5>>5 watu.
Hawa watu 5 wanaweza kuchimba paundi 500 ya makaa ya mawe kwa siku kwa sababu 1000 / 5 = <<1000/5=200>>200.
Watu 5 wanaweza kuchimba paundi 40,000 ya makaa ya mawe kwa siku 80 kwa sababu 40,000 / 500 = <<40000/500=80>>80
