You can put this solution on YOUR website!
The formula to use is:
Where:
h=height
v=velocity
t=time in seconds
Plug in the knowns:

Differenate and multiply the results by 2.



Multiply the results by 2:
2(2.03125)=4.0625

Or you can factor it:
65t-16t^2

16t(4.0625-t)

t=0 or t=4.0625. ---> this  would be a proving statement, if you were asked to prove it.





Hence, the time it would take is 4.06 seconds.

Paul.
