question 29

Multiple Choice

On rural highways, the average speed S (in miles per hour) is related to the amount of curvature C (in degrees) of the road. Suppose that on a straight road (C = 0) , the average speed is 47.5 miles per hour and this decreases by 0.65 mph for each additional degree of curvature. Find the formula expressing S as a linear function of C.

• A)S = 0.65C + 47.5
• B)S = 47.5C + 0.65
• C)S = 47.5C - 0.65
• D)S = -0.65C + 47.5
