Homework Help: Velocity vs Time graphs

  1. Sep 8, 2013 #1
    Hello guys,

    I am having a hard time understanding velocity vs time graphs. In one of my homework problems I was given a velocity vs time graph and asked to find the average speed in a time interval of 9 seconds. I am unsure how to go about this.

    Also, how would I find displacement at a certain time given a velocity vs time graph?

    Any help would be greatly appreciated. I have uploaded the graph as well so that you guys can know what I'm talking about.

    Hello. Welcome to PF.

    Could you please upload that in a pdf or perhaps an image (jpeg or png or w/e)? I don't have word and I won't be able to see the graph. Also, it's good practice to upload pdf's or images. :P

    Let me know if this helps.

    I'm not sure if I'm allowed to link to Khan Academy, but oh well.
