The temperature at noon is calculated by adding the temperature rise of 6° to the initial temperature of -4° at 5 am. Therefore, the temperature at noon was 2°.
The student has asked what the temperature was at noon, given that it was -4° at 5 am and it rose by 6° by noon. To find the temperature at noon, we simply need to add the increase in temperature to the initial temperature at 5 am.
Initial temperature at 5 am: -4°
Rise in temperature by noon: +6°
Temperature at noon = Initial temperature + Rise in temperature
Temperature at noon = -4° + 6°
Temperature at noon = 2°
Therefore, the temperature at noon was 2°.
