Pls help ASAP

A rubber duck was placed on the surface of a pool. As somebody jumped into the pool close to the duck, the duck bobbed up and down on the water surface. Its vertical
motion was plotted on the graph below.

The motion can be described by the equation:
Ae-0.2t cos(5t)
where A is the maximum amplitude of 10cm.
What is the average vertical velocity of the rubber duck between 1.1s and 3.2s ? Assume positive means upwards, and negative downwards. Be sure your calculator is in
radian mode for this question.
