As it is stated in this item, in order to determine the amount of time it takes to hit the ground, the equation 
                           -16t² + 1600 = 0

Transpose the terms without variable to the other side of the equation,
                             -16t² = -1600

Divide the equation by -16.
                               t² = 100

Solve the value of t by getting the square root of the equation.
                               t = +/- 10

Thus, it will take the object 10 seconds to reach the ground.
