Rate Slope

I am not sure on how to determine the average rate of depth change for the1-second time interval centered at this midpoint. That is, determined the average rate of depth change between t=49.5 sec and t=50.5 sec....It is the second part of question #2 in the work sheet Intro to Rates and Slopes....Thanks.

In the question you ask you are given the two clock times, and you know the function.
To find the average rate of deptn change between two clock times, you plug your two t values into the function to find the two depths. Then divide the change in depth by the change in clock time.
