Simply plug in the time period over which you want to know the average velocity into the distance equation, and then divide that answer by the time duration.
I.e for t=.5 then y=40*.5-16*.5^2=16.
then divide that answer by the time to get average velocity: avgV=y(t)/t=16/.5=32
Don't overthing the problems.
The average velocity will determine the position of the ball at time t, so take the position and divide it by that time.

By this logic, the answer to the second value, 0.1, is avgV=y(t)/t=3.84/0.1 = 38.4
I don't think you can ever overthink a problem but you can definitely
underthink it!
This is the incorrect answer. Can you figure out what you missed?
At least you are correct in saying that this is simple and not a question of calculus...
