Yes, you can calculate the average temperature of a day if you know the highest and lowest temperatures. To find the average, you would sum up the highest and lowest temperatures and divide the result by 2.
Average temperature = (Highest temperature + Lowest temperature) / 2
For example, let's say the highest temperature recorded during a day is 30 degrees Celsius and the lowest temperature is 15 degrees Celsius. The average temperature would be:
Average temperature = (30 + 15) / 2 = 45 / 2 = 22.5 degrees Celsius
Therefore, the average temperature for that day would be 22.5 degrees Celsius.
