Question

A windmill has eight equally spaces blades that rotate in the clockwise direction How many degrees must blade P rotate to reach location blade U?

a
225 degrees
b
45 degrees
c
120 degrees
d
180 degrees

Answer 1

Option (A)

Explanation:

Windmill is in the shape of a circle and each blade of the windmill is equally spaced.

There are 8 spaces in the windmill shown.

Therefore, angle between each blade =
`(360)/(n)`

Where n = number of blades

Angles between each blade =
`(360)/(8)`

= 45°

To reach the position of blade U by blade P will cover 5 angles between the blades.

Therefore, angle of rotation covered by P to reach U = 5×45° = 225°

Option (A) will be the correct option.
