3. Two hours after the start of a 100-kilometer bicycle race, a cyclist passes the 80-kilometer mark while riding at a velocity of 45 kilometers per hour. (A) Find the cyclist's average velocity during the first two hours of the race. B (B) Let f(x) represent the distance traveled (in kilometers) from the start of the race (x = 0) to time x (in hours). Find the slope of the secant line through the points (0, f(0)) and (2, f(2)) on the graph of y = f(x). (C) Find the equation of the tangent line to the graph of y = f(x) at the point (2, f(2)).
