The following sketch represents the distance d (in miles) that Kevin was from home as a function of time t (in hours). Answer the questions based on the graph shown to the right. In parts (a) to (g), how many hours elapsed and how far was Kevin from home during this time? Complete parts (a) through (i).

A coordinate system has a horizontal t-axis and a vertical d(t)-axis that intersect at (0, 0). The following plotted points are connected by line segments from left to right: (0, 0 (3, 9 (3.3, 9 (3.9, 0). A curve rises from left to right from a plotted point at (4.2, 0) to a plotted point at (4.8, 8.5). The curve then travels horizontally to a plotted point at (5, 8.5) where it then falls from left to right at a decreasing rate to a plotted point at (6.2, 0).
