Final answer:
The better estimate for the temperature of each smaller bowl of soup is 90°F.
Step-by-step explanation:
The better estimate for the temperature of each smaller bowl of soup is 90°F.
When the 300-milliliter bowl of soup is divided equally into three smaller bowls, each smaller bowl will contain the same amount of soup as the original bowl. Since the soup is at a temperature of 90°F before being poured into the smaller bowls, it will remain at the same temperature.
Therefore, each smaller bowl of soup will have a temperature of 90°F.
