Find the instantaneous velocity of a point in the graph.

This link has the exact graph that relates to my question.
I have tried answering the question however, the formula that is provided in my book for instantaneous velocity is change of V/change of t as the limit of t approaches 0. The problem is that when they are asking me the instantaneous speed of the first point like A , what is the second point that I need to use to input the change of velocity and t on the formula?
I really appreciate the help. Thank you.
