25) Mary is competing in the 100-meter dash. 6.7 Suppose that her position is described by the 0 41 position function p (t) , where t is the time in 36.2 seconds and p (t) is her position in meters. There is not enough information. If she finishes the race (100 meters) in 15 seconds, and her instantaneous velocity at t = 1.5 seconds is 6.2 meters/second, what is the slope of the line tangent to the graph of p (t) att = 1.5
