Just a math question?
A microwave can reheat 1 cup of coffee in 30 seconds. It takes a coffee-maker 10 minutes to brew 12 cups of coffee. If the coffee-maker requires 900 watts of power and the microwave requires 1200 watts of power, does it require more energy to brew 12 cups with the coffee-maker or reheat 12 cups of coffee in a microwave?
