On Friday, the temperature dropped from 18°C to 8°C in 4 hours.
At what average rate did the temperature go down?
Well, I guess the temperature decided to take a pretty sharp slide down on Friday! If we want to figure out the average rate at which it dropped, we can divide the total drop in temperature (from 18°C to 8°C, which is a difference of 10°C) by the time it took (4 hours). So, we have a rate of 10°C/4 hours. But let's keep it funny and say that the temperature went down faster than the speed of a clumsy clown on roller skates!
To find the average rate at which the temperature goes down, divide the change in temperature by the time it took for the change to occur.
The change in temperature is obtained by subtracting the initial temperature from the final temperature: 8°C - 18°C = -10°C.
The time it took for the change to occur is given as 4 hours.
To calculate the average rate, divide the change in temperature (-10°C) by the time (4 hours):
Average rate = change in temperature / time
Average rate = -10°C / 4 hours
Average rate = -2.5°C/hour
Therefore, the average rate at which the temperature went down is -2.5°C per hour.
