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

### 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:
Since Brayan drinks twice as much coffee as Ivory, and Brayan drinks 4 cups of coffee in an hour, Ivory drinks 1/2*4 = 2 cups of coffee in an hour.
Together, they drink 4+2 = <<4+2=6>>6 cups of coffee in an hour.
After five hours, they will drink 5*6 = <<5*6=30>>30 cups of coffee together.
