Final answer:
The temperature difference between Québec, Canada, at –9°F and Newfoundland at 12°F is 21°F. correct answer is D.
Step-by-step explanation:
The question at hand is calculating the temperature difference between two places with different temperatures. The temperature in Québec, Canada, is –9°F, and in Newfoundland, it is 12°F.
To find the temperature difference, we subtract the lower temperature from the higher temperature:
Temperature in Newfoundland - Temperature in Québec = 12°F - (–9°F) = 12°F + 9°F = 21°F. Therefore, the temperature difference between Québec and Newfoundland is 21°F.
The temperature difference between Québec, Canada, and Newfoundland can be calculated by subtracting the temperature in Québec from the temperature in Newfoundland. In this case, the temperature in Québec is -9°F and the temperature in Newfoundland is 12°F.
