Find the average rate of change for the situtation.

You climb down 78 stairs in 6 minutes.

To find the average rate of change, we need to divide the change in the quantity by the change in time.

In this case, the change in the quantity is the number of stairs climbed down, which is 78. The change in time is 6 minutes.

Average rate of change = (Change in quantity) / (Change in time)
= 78 stairs / 6 minutes
= 13 stairs per minute

Therefore, the average rate of change for climbing down the stairs is 13 stairs per minute.

To find the average rate of change, we need to divide the change in the variable of interest (in this case, the number of stairs) by the change in the time variable.

The change in the number of stairs is given as 78 stairs. The change in time is given as 6 minutes.

Therefore, the average rate of change is calculated as follows:

Average Rate of Change = Change in Stairs / Change in Time
= 78 stairs / 6 minutes
= 13 stairs per minute

So, the average rate of change for this situation is 13 stairs per minute.
