Final answer:
It will take 280 seconds for the ice cube to melt in the microwave oven assuming it's using its power effectively on the ice.
Explanation:
To find out how long it will take to melt the ice, we need to use the formula time (seconds) = energy (joules) / power (watts). Since it takes 32200 joules to melt the ice and the microwave delivers 115 joules every second (since 1 watt = 1 joule/second), the calculation would be 32200 joules / 115 watts.
When we do the math, we find that:
Time = 32200 J / 115 W = 280 seconds.
Therefore, it will take 280 seconds for the ice cube to melt in the microwave oven assuming it's using its power effectively on the ice.
