Answer :
Final answer:
The range of motion of the wiper blade is the distance the tip travels; therefore, it is equal to the length of the wiper blade itself, which is 16 inches. The correct answer is option b).
Explanation:
The student is asking about the range of motion of a wiper blade, specifically related to the arm and pivot point of the wiper system on a vehicle. To find the range of motion, we consider the distance from the pivot point to the tip of the wiper blade. Since the arm is 22 inches, but only 6 inches of it is from the pivot point to the wiper blade's mounting, the remaining 16 inches represent the length of the blade itself. Therefore, when the wiper pivots, the tip of the blade will trace an arc equal to the length of the blade, which is 16 inches. So, the correct answer is b) 16 inches.
