when an object is thrown vertically in the air, the velocity of the object before returning back to the ground is zero and velocities for upward movement are always negative

The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
