1. The problem statement, all variables and given/known data If a 5 amp unit can cool 4 cups of water from 75 to 50 degrees fahrenheit in one hour, what temperature could a 30 amp unit cool 128 cups of water in the same amount of time? Is there enough information here to get an idea about what the 30 amp unit would do? If so where would one start? 2. Relevant equations 3. The attempt at a solution I am not too sure where to start.
