I'm afraid your question does not have enough information.
Please give diagram, or complete description of the problem...

In general you will have a quadratic equation in t, having 2 solutions.

One solution is normally when a vertically moving object is on the way up, and the other is when it is on the way down.

The actual equation depends on the details of the question...
