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

### Instruction:
Ivory and Brayan are doing school projects with a tight deadline and have to stay up late to complete everything. They prepare coffee to help them stay focused. If Brayan drinks twice as much coffee as Ivory, and Brayan drinks 4 cups of coffee in an hour, calculate the total number of cups of coffee they drink together in 5 hours.

### Response:
 Ikiwa Brayan anakunywa vikombe 4 vya kahawa kwa saa, mara mbili ya Ivory, basi Ivory anakunywa vikombe 4 / 2 = <<4/2=2>>2 vya kahawa kwa saa.
Pamoja, wanakunywa vikombe 4 + 2 = <<4+2=6>>6 vya kahawa kwa saa.
Baada ya masaa 5, watakunywa jumla ya vikombe 5 * 6 = <<5*6=30>>30 vya kahawa.
