Is it possible for a distance-versus-time graph to be a vertical line? explain

It is impossible for a dt-graph to have a vertical line. This would mean that you are at many places at one point in time. It simply can't be done, because we can't teleport lol. You can, however, have a line that is REALLY steep. This would mean that you're travelling really fast. (Covering large amounts of distances in short spans of time) Hope this helped!

So what is the question
