9. Distance… Sally rides her scooter along a straight road from home to the mall, starting at home at time t=0 minutes and arriving at the mall at time t=20 minutes. During the time interval, minutes, her velocity, in miles per minute, is modeled by the piecewise linear function whose graph is shown on the next slide.
