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

### Instruction:
Carson is going to spend 4 hours at a carnival. The wait for the roller coaster is 30 minutes, the wait for the tilt-a-whirl is 60 minutes, and the wait for the giant slide is 15 minutes. If Carson rides the roller coaster 4 times and the tilt-a-whirl once, how many times can he ride the giant slide? (Wait times include the time actually spent on the ride.)

### 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
