Preview Activity 1.5.1. One of the longest stretches of straight (and flat) road in North America can be found on the Great Plains in the state of North Dakota on state high- way 46, which lies just south of the interstate highway I-94 and runs through the town of Gackle. A car leaves town (at time t = 0) and heads east on highway 46; its posi- tion in miles from Gackle at time f in minutes is given by the graph of the function in Figure 1.5.1. Three important points are labeled on the graph; where the curve looks linear, assume that it is indeed a straight line. b. Find the slope of the line between the points (57, 63.8) and (104, 106.8). What are the units on this slope? What does the slope represent?
