    Help with a piecewise function problem

    I'm having trouble figuring out where to begin on this piecewise function problem and expressing a as a piecewise function of t.


    A certain ironman triathlon consists of a 2.4 mile swim, followed by a 112 mile bike ride, and ends with a 26 mile run.
    A contestant in this competition swims at a rate of 1.2 mi/hr., bikes at a rate of 14 mi/hr., and runs at a pace of 4 mi/hr.


    Let t to be the number of hours since the contestant started the race, and let s=s(t) be the total distance covered at time t. Assume no time is lost in transition from one event to another.

    Do you mean s and not a? So are you having trouble expressing s(t) even on the first leg of the triathlon? If not, that's where you begin.
