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

### Instruction:
Jerry can run from his house to his school and back in the time it takes his brother Carson to run to the school. If it takes Jerry 15 minutes to make a one-way trip from his house to his school and the school is 4 miles away, how fast does Carson run in miles per hour?

### Response:
 Jerry anaweza kufanya safari ya kwenda na kurudi kutoka nyumbani kwake hadi shule kwa dakika 15.
Kwa hivyo anaweza kufanya safari moja kutoka nyumbani kwake hadi shule kwa dakika 15/2 = <<15/2=7.5>>7.5 dakika.
Shule iko maili 4 kutoka nyumbani kwake.
Kwa hivyo Jerry anakimbia maili 4 katika dakika 7.5.
Kwa saa moja, Jerry anakimbia maili 4/7.5 dakika x 60 dakika = <<4/7.5*60=48>>48 maili.
Carson anakimbia maili 4 katika muda sawa na Jerry anakimbia maili 4 na kurudi.
Kasi ya Carson ni maili 48 kwa saa.
