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

### Instruction:
Samuel took 30 minutes to finish his homework while Sarah took 1.3 hours to finish it. How many minutes faster did Samuel finish his homework than Sarah?

### Response:
 Kwa kuwa kuna dakika 60 katika saa 1, basi saa 1.3 ni sawa na 1.3 x 60 = <<60*1.3=78>>78 dakika.
Hivyo, Samuel alikuwa dakika 78 - 30 = <<78-30=48>>48 kwa kasi zaidi kuliko Sarah.
