Question

A ferris wheel has 16 cars spaced equal distances apart. The cars are numbered in order from 1-16. What is the measure of the angle of rotation that will map the position of car 16 onto the position of car 13?

A) 22.5
B) 45
C) 67.5
D) 90

I think it's D

Answer 1

the cars are 360/16 = 22.5° apart.
car 16 is 3 positions from car 13. So, a rotation of 67.5° will move car 16 to car 13's position.

Answer 2

thank you !
