Help Instantaneous velocity

  1. Sep 21, 2013 #1
    The position of a particle moving in a straight line during a 10–second trip is s(t) = 3t2 − 3t + 5 cm.Find a time t at which the instantaneous velocity is equal to the average velocity for the entire trip

    s'(t)=6t-3=6(10)-3=57s instantenous velocity but I don't know how to get average

    Please don't post the same problem in different forums.

    See, you've confused yourself because there may be different replies in your other post.

    Average velocity is defined as change in position divided by time elapsed.
