    Average Speed Anyone?
    I have a lab report due tomorrow but I can't figure out the mathematics of it.

    Here's my problem:

    I have a data chart showing distance and time, and I need to find the average speed.

    There are 31 pieces(?) of data.
    Each one has a measurement of distance and its time.
    I need to find the average speed of alll these and I can't seem to do it.
    My problem is that the distances are measured in cm,
    But the time is measured in 1/60th of a second each.

    If the time stays consistent... meaning that there's a 1/60th of a second increase each time, but the distance increases each time, HOW DO I FIND THE AVERAGE SPEED?

    Thanks.
    Peace. :cool:

    Unless you explain fully, all I can say is

    Average speed = total distance covered/total time elapsed

    You have distance (s) and time (t)
    The integral of ds/dt is speed.
    Average speed is 1/(t2-t1)*integral ds/dt from t1 to t2
    So integrate by parts and divide by the time.

    I already answered your question here: https://www.askmehelpdesk.com/math-s...an-156364.html but I agree with terryg752.
    I'm not really sure what KISS is thinking, certainly not keeping with their name ;)

    * Man - I think I read too much into the problem. Let me crawl under a rock for a while.
