The formula d = 1.2ť? + t + 1 expresses a car's distance (in feet to the north of an intersection, d, in terms of the number of seconds t since the car started to move
a. As the time t since the car started to move increases from t = 2 tot = 5 seconds, what constant speed must a truck travel to cover the
