Question

Increases in temperature are recorded with positive numbers. decreases in temperature are recorded with negative numbers. once the sun went down, the outside temperature decreased \[2 \degree \text{c}\] per hour over \[4\] hours. what is the total change in temperature over the \[4\] hours?

Answer 1

To calculate the total change in temperature, multiply the rate of temperature decrease per hour (2°C) by the number of hours (4), resulting in a total temperature decrease of 8°C.

Step-by-step explanation:

The student is asking about the total change in temperature over a period of time when the temperature is decreasing 2°C per hour over 4 hours. To find the total change, we need to multiply the rate of decrease per hour by the number of hours.

Total change in temperature = Rate of decrease per hour × Number of hours

Total change in temperature = 2°C/hour × 4 hours

Total change in temperature = 8°C.

Therefore, the total change in temperature over the 4 hours after the sun went down is a decrease of 8°C.
