Prepare a table for such a situation. Say a ball is thrown up with a speed of 50m/s. After each second find out its speed until it reaches the highest point. Record these into a table.

On the way down you can use the same values of speed because you will find that the speed is the same on the way up and way down.

Next plot these values on a graph paper.

If the ball is moving at a constant speed, then its speed does not change. So its graph will be a straight line parallel to the time axis. From the graph you can find the distance travelled by taking the area between these two points on the time axis.
