The graph above indicates that at 60 miles per hour the distance traveled depends on time. In other words, distance is a function of rate and time. At one hour a distance of 60 miles is covered. At 2 hours a distance of 120 miles is covered. According to the graph what distance is covered at 3 hours? 4 hours? Finish the table below.
