Braking distance for automobiles traveling at x miles per hour, where 20 x 70, can
Question:
Braking distance for automobiles traveling at x miles per hour, where 20 ≤ x ≤ 70, can be modeled by the rational function
(a) Use graphing to estimate x to the nearest unit when d(x) = 300.
(b) Complete the table for each value of x.
(c) If a car doubles its speed, does the braking distance double or more than double? Explain.
(d) Suppose that the automobile braking distance doubled whenever the speed doubled. What type of relationship would exist between the braking distance and the speed?
