The temperature dropped 3°C every hour for 9 hours. What was the total number of degrees the temperature changed in the 9 hours?
To find the total number of degrees the temperature changed in 9 hours, we need to calculate the sum of the temperature changes for each hour.
Given that the temperature dropped by 3°C every hour for 9 hours, we can simply multiply the rate of change (3°C) by the number of hours (9 hours) to get the total change in temperature.
Therefore, the total number of degrees the temperature changed in the 9 hours is 3°C multiplied by 9 hours, which equals 27°C.
