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

### Instruction:
A man loves to go hiking.  He knows that he has to pack about .5 pounds of supplies for every mile he hikes.  He plans to go for a very long hike.  He knows that he can get 1 resupply during the hike that will be 25% as large as his first pack.  He can hike at a rate of 2.5 mph.  He is going to hike 8 hours a day for 5 days.  How much does he need to bring with his first pack?

### Response:
 Anapanga kusafiri kwa masaa 8 * = 40.
Hii inamaanisha atakuwa amesafiri kwa jumla ya maili 40 * 2.5 = <<40*2.5=100>>100.
Hivyo anahitaji paundi 100 * 0.5 = <<100*0.5=50>>50 za vifaa.
Kwa vifaa vingine anavyoweza kupata, anaweza kupata hadi 1 + 0.25 = 1.25 mara ya mfuko wake wa kwanza.
Hii inamaanisha mfuko wake wa kwanza lazima uwe na uzito wa paundi 50 / 1.25 = <<50/1.25=40>>40.
