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

### Instruction:
 Kufanya km 3, Ben alitembea kwa masaa 2. Akiendelea kwa kasi ile ile, itamchukua muda gani kwa dakika kusafiri km 12?


### Response:
 Tuna km 12 / km 3 = <<12/3=4>>4. Hivyo, umbali uliosafiriwa kwa km 12 ni mara 4 zaidi ya km 3. Muda uliotumika pia utakuwa mara 4 zaidi.
Hivyo, masaa 2 x 4 = <<2*4=8>>8 masaa.
Kuna masaa 8 = 480 dakika.
