A rock is thrown from the top of a tall building. The formula h = -16t + 234 describes the height of the rock, h in feet, t seconds after the rock is thrown. How long after the rock is thrown does it hit the ground?
-----------
h = -16t + 234
When h = 0, it hits the ground.
But I think your equation is wrong.
