Homework Help: Finding total time of a running rabbit

  1. Oct 4, 2011 #1
    1. The problem statement, all variables and given/known data
    A rabbit runs in a straight line with a velocity of +1.5 m/s for a period of time, rests for 10s, and then runs again along the same line at +0.60 m/s for an unknown amount of time. The rabbit travels a total distance of 1200 m, and its average speed is 0.80 m/s. (a) What is the total time the rabbit spends running at 1.5 m/s? (b) How long does it spend running at 0.60 m/s?


    2. Relevant equations
    V = d/t
    a = (v2-v1) /t
    I dont know if there is any other formulas you could use for this question


    3. The attempt at a solution

    t = d/V
    Total time = 1200 / 0.8 = 1500 sec


    -------------------------------------------
    Answer for a: 340 sec
    Answer for b: 1200 sec

    I want to know how to get these answers

    1.5x + 0.6y = 1200(0.8)

    Hopefully that helps. If you don't understand where I got that from or what to do from here, let me know.

    what does that equation even mean? Are the "x" and "y" the time intervals?
