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

### Instruction:
Haley is getting ready to watch a comet fly over her house. She spends two hours shopping for a telescope, half an hour getting everything set up in the backyard, three times the setup time making snacks, and 20 minutes watching the comet. What percentage of the total time she spent on all those activities was spent watching the comet, rounded to the nearest percent?

### Response:
 Kwanza, geuza muda wa ununuzi wa Haley kuwa dakika: masaa 2 * dakika 60/saa = <<2*60=120>>120 dakika
Kisha geuza muda wa kuweka tayari kuwa dakika: .5 masaa * dakika 60/saa = <<.5*60=30>>30 dakika
Kisha pata jumla ya muda anautumia kutengeneza vitafunwa: 3 * dakika 30 = <<3*30=90>>90 dakika
Kisha pata jumla ya muda anautumia kwenye shughuli zote tatu: dakika 120 + dakika 30 + dakika 90 = <<120+30+90=240>>240 dakika
Kisha gawanya muda anautumia kuangalia kometi na jumla ya muda na kuzidisha kwa 100% ili kubadilisha kuwa asilimia: dakika 20 / dakika 240 = 8.333...%, ambayo inakadiriwa kuwa 8%
