Answer:To find the rate at which the temperature is changing, we need to calculate the temperature difference between 3pm and 1pm, and then divide it by the time difference.
Given that the temperature at 1pm is 80 degrees and at 3pm is 92 degrees, the temperature difference is 92 - 80 = 12 degrees.
The time difference between 3pm and 1pm is 3 - 1 = 2 hours.
To find the rate at which the temperature is changing, we divide the temperature difference by the time difference: 12 degrees / 2 hours = 6 degrees per hour.
Therefore, the temperature is changing at a rate of 6 degrees per hour.
