Question

A windmill has eight equally-spaced blades that rotate in the clockwise direction.

How many degrees must blade p rotate to reach the location of blade u?
A: 120
B: 225
C: 45
D: 180

Answer 1

Blade p must rotate 360 degrees to reach the location of blade u.

Step-by-step explanation:

To determine how many degrees blade p must rotate to reach the location of blade u, we need to first determine the angle between each blade in the windmill. Since there are 8 equally-spaced blades, the angle between each blade is 360 degrees divided by 8, which is 45 degrees.

Since blade p is initially at the same position as blade u, it needs to rotate one complete revolution (360 degrees) to reach the location of blade u.

Therefore, blade p must rotate 360 degrees to reach the location of blade u.
