Is there a way to handle a formula question with multiple answers?

 

For example, a ball is tossed up and the student is asked to calculate the time when the ball is in a particular position. This is solved through a quadratic equation and there are two answers: the time up and the time down.

 

In this case, the question could be rearranged to ask what is the time up OR what is the time down? However, what if the question couldn't be rearranged. What are the options? How are teachers getting around this situation? Are teachers rewriting the question or is there an approach being used that someone is will to share?
