Create a piecewise function of the following scenario where D(t) is the total distance walked in miles as a function of time T (in minutes) You begin a walk from your home at a fast pace of 6 miles per hour for 30 minutes. You rest for 15 minutes, and then you continue walking at a leisurely pace of 1 mile per hour for 30 minutes."

I have D(t)=1/10t when 0<=t<=30
D(t)=3
i need help with the last one of 45<t<=75

i initially put in 3+1/60t but that is incorrect

  1. D(t) =
    1/10 t for 0 <= t <= 30
    3 for 30 < t <= 45
    3 + 1/60 (t-45) for 45 < t <= 75

    Looks good to me. Why do you say it is wrong?
