~~~~~~~~~~~~~~~~~~
I will show you very simple way to solve this problem.
You have a quadratic function; its plot is a parabola, inverted downward
h(t) = 80t - 16t^2 = 16t(5 - t).
Its x-intercepts are t= 0 and t= 5.
The parabola has the maximum exactly half way between x-intercepts, i.e. the maximum is at t = = = 2.5 seconds.
So, it will take 2.5 seconds to reach the maximum height. ANSWER
Solved.
