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

### Instruction:
Jake's dad can drive the distance from their house to the water park in 30 minutes. He spends half that journey driving 28 miles per hour and the other half driving 60 miles per hour on the highway. If Jake can bike 11 miles per hour, how many hours will it take him to bike to the water park?

### Response:
 Kwanza tafuta muda wa nusu ya safari ya baba ya Jake: dakika 30 / 2 = <<30/2=15>>15 dakika
Kisha badilisha muda huo kuwa saa: 15 dakika * 1 saa/60 dakika = .25 saa
Kisha tafuta umbali ambao baba ya Jake anasafiri kwa kasi ya maili 28 kwa saa: .25 saa * maili 28 kwa saa = <<.25*28=7>>7 maili
Kisha tafuta umbali ambao baba ya Jake anasafiri kwa kasi ya maili 60 kwa saa: .25 saa * maili 60 kwa saa = <<.25*60=15>>15 maili
Kisha ongeza umbali huo ili kupata umbali jumla kuelekea hifadhi ya maji: 7 maili + 15 maili = <<7+15=22>>22 maili
Kisha gawanya umbali jumla kwa kasi ya Jake ili kujua muda atakaotumia: 22 maili / maili 11 kwa saa = <<22/11=2>>2 saa
