Erin and the cats leave at noon, starting slowly , then picking up speed and finally slowing back down. Avi leaves the parking lot at 1pm and drives at a constant rate of 50 miles per hour. The graph below shows the velocity functions over time for both Avi and Erin, with some regions shaded. . . . . . . . . .. . . . . . . . 1 . . . . . . . . . . . . .. .. . . . . . . . . .:.
