Description: How would I find a formula for this and evaluate s(72) 11A driver's reaction.distance is r(x) =x and braking distance is b(x) =12(a) Find a formula s(x) that computes the stopping distance for this driver traveling at x miles per hour.(b) Evaluate s(

Given that the reaction distance rx=1112x and the braking distance bx=x29. (a) The stopping distance is given by the sum of the reaction distance and the braking distance. Hence, sx=rx+bx=1112x+x29 Thus, the formula for stopping distance is sx=1112x+x29. b. To evaluate s72, substitute x=72 in sx=1112x+x29 as follows. s72=1112×72+7229=66+576=642 Hence, the value s72=642 miles. The value s72 gives the stopping distance when the speed is 72 miles per hour. So, when the driver runs the vehicle at a speed of 72 miles per hour, the distance covered before stopping is 642 miles.
