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.
Thoughts? Step-by-step reasoning:
If Brayan drinks 4 cups of coffee in an hour, twice what Ivory drinks, then Ivory drinks 4 / 2 = 2 cups of coffee in an hour. Together, they drink 4 + 2 = 6 cups of coffee in an hour. After 5 hours, they will drink 5 * 6 = 30 cups of coffee together.
Thus, the answer is 30.
