The temperature dropped 18 degrees Fahrenheit in 6 hours last night. The equation below can be used to find n, the average number of degrees the temperature changed each hour during that period.

-18/6 = n

What was the average rate of change per hour last night

every thinggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg

-18/6 means divide -18 by 6

so -3

Yes, -3 degrees per hour

To find the average rate of change per hour last night, we can use the equation:

Average rate of change per hour = Total change in temperature ÷ Total time

In this case, the total change in temperature is given as -18 degrees Fahrenheit, and the total time is given as 6 hours. So, we can substitute these values into the equation:

Average rate of change per hour = -18 ÷ 6

By dividing -18 by 6, we get:

Average rate of change per hour = -3 degrees Fahrenheit per hour

Therefore, the average rate of change per hour last night was -3 degrees Fahrenheit.
