A study of average driver speed on rural highways by A. Taragint found a linear relationship between average speed S, in miles per hour, and the amount of curvature D, in degrees, of the road. On a straight road (D 0), the average speed was found to be 46.26 miles per hour. This was found to decrease by 0.746 mile per hour for each additional degree of curvature. (a) Find a linear formula relating speed S to curvature D. S(D)= (b) Express using functional notation the speed for a road with curvature of 23 degrees. S 23 Calculate that value.
