Upper D left-parenthesis t right-parenthesis ??
really? This is math, not English!
D(t) =
3(t/60) if 0<t<=30
1/2 if 30<t<=40
1/2 + 1((t-40)/60) if t>30
Create a piecewise function of the following scenario where Upper D left-parenthesis t right-parenthesis 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 3 miles per hour for 30 minutes. You rest for 10 minutes, and then you continue walking at a leisurely pace of 1 mile per hour for 25 minutes."
How far have you walked at the end of 23, 39, and 55 minutes?
