    |dw:1328839319753:dw| what is the velocity at 3s?

    velocity is the rate of change of distance so it will be the slope at that point.

    V=m/s so take the distance and divide by time. It helps to look at Units in physics to figure out what equation to use.

    that's what I was told but I don't know how to get is

    Is the question the change in velocity? At 3 secs it would be 1 m/s, but that doesn't seem right.

    no it says 'What is the velocity at 3.0 seconds?'

    find the slope at the exact place by drawing a line an looking for the slope

    if its a distance-time graph then how is the distance decreasing. i guess its a displacement-time graph, then velocity at 3 seconds=3.5-3.0/3.0=1/6 m/s
