A body thrown with an initial speed of `96 ft//sec` reaches the ground after `(g = 32 ft//sec^(2))`

A body thrown with an initial speed of 96 ft/s reaches the ground after (g=32 ft/s^2)

A stone is thrown upwards from the top of a tower with some initial speed and it reaches the ground in 16 seconds. Now it is thrown with the same initial speed downward and it reaches the ground in 9 sec . In how much time will it reach the ground if the stone is allowed to fall freely under gravity from the same place ?
