    Minimum Distance

    Thanks. The same equation now asks me:

    What is the TOTAL distance the particle travels between time 0 and 10:?


    I followed the directions and set it up like this but am getting the wrong answer:


    abs(11-0)+abs(-16-1)+abs(740-16)


    I used the following hint:

    The TOTAL distance traveled: |s(A)- s(0)|+ |s(B)- s(A)|+ |s(10)- s(B)|


    Thanks again for the help!

    what equation is that? s(t)= 2t^3 - 15 t^2 + 24 t ?

    According to CaptainBlack, A = 1, B = 4, s(10) = 740

    so s(A) = 11
    s(B) = -16

    so distance travelled = |11 - 0| + |-16 - 11| + |740 + 16|

    ah, maybe you made the mistake here, for the 2nd abs you had -1 not -11 and for the last you had 740 - 16, but it should be 740 - (-16) = 740 + 16

    so distance traveled = 11 + 27 + 756 = 794

    where did you get this hint from by the way? oh, nevermind, it seems to be common sense now that i look at it
