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

### Instruction:
 Carson anatarajia kutumia masaa 4 katika tamasha la burudani. Kusubiri kwa roller coaster ni dakika 30, kusubiri kwa tilt-a-whirl ni dakika 60, na kusubiri kwa giant slide ni dakika 15. Ikiwa Carson atapanda roller coaster mara 4 na tilt-a-whirl mara moja, anaweza kupanda giant slide mara ngapi?


### Response:
 Kwanza tafuta muda jumla wa kusubiri kwa roller coaster: 30 dakika/safari * 4 safari = <<30*4=120>>120 dakika
Kisha tafuta muda jumla Carson anatumia katika tamasha la burudani: 4 masaa * 60 dakika/masaa = <<4*60=240>>240 dakika
Kisha toa muda jumla uliotumika kwenye roller coaster na tilt-a-whirl kutoka kwenye muda jumla katika tamasha ili kupata muda uliobaki kwa ajili ya giant slide: 240 dakika - 120 dakika - 60 dakika = <<240-120-60=60>>60 dakika
Kisha ugawe muda uliobaki kwa muda wa kusubiri kwa giant slide ili kujua mara ngapi Carson anaweza kuipanda: 60 dakika / 15 dakika/safari = <<60/15=4>>4 safari
