To find the average rate of change, we need to divide the change in position by the change in time.
The change in position is the difference between the highest point above the water (3.5 m) and the lowest depth below the water (-10 m), which is 3.5 m - (-10 m) = 3.5 m + 10 m = 13.5 m.
The change in time is given as 12.5 seconds.
The average rate of change is therefore 13.5 m / 12.5 s = 1.08 m/s.
Rounding to the nearest hundredth, the average rate of change in position is approximately 1.08 m/s.
The dolphin, just above the surface of the water it reached the attitude of 3.5 m above the surface of the water, and then dove 10 m below the surface of the water and went from its highest point above the water to its lowest step in 12.5 seconds interpreted the quotient to describe the average rate of change the office position give your answer to the nearest hundreds.
