Chapter 5, Problem 89(choose chapter or problem)
Taking into account reaction time, the distance d (in feet) that a car requires to come to a complete stop while traveling r miles per hour is given by the function d1r2 = 6.97r - 90.39 (a) Express the speed r at which the car is traveling as a function of the distance d required to come to a complete stop. (b) Verify that r = r1d2 is the inverse of d = d1r2 by showing that r1d1r22 = r and d1r1d22 = d. (c) Predict the speed that a car was traveling if the distance required to stop was 300 feet.
