The sentence is wrong in the sense that the centrifugal force was actually the reason why the clothes in the washing machine help it dry. But contrary to the belief, the reason why clothes are easier to dry in the washing machine is because of the holes that were drilled into the washing machine. These holes allow the water to escape from the clothes and enter into these holes so that they are drained away from the clothes.

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).
