Question

1. at noon the temperature was ( 1^circ ) c. over the next 3 hours the temperature dropped another 6 degrees. then every hour until 4:00 the temperature rose 3 degrees. what was the temperature at 4:00?

Explanation:

Step1: Determine initial temperature

At noon (12:00), temperature is \(1^\circ \text{C}\).

Step2: Calculate temperature after 3 hours (by 3:00)

Temperature dropped 6 degrees, so new temperature is \(1 - 6 = -5^\circ \text{C}\).

Step3: Calculate temperature at 4:00

From 3:00 to 4:00 (1 hour), temperature rose 3 degrees. So temperature at 4:00 is \(-5 + 3 = -2^\circ \text{C}\).

Answer:

The temperature at 4:00 was \(-2^\circ \text{C}\)
