My question that i'm suppose the answer is: two particles, a and b, are in uniform circular motion about a common center. the acceleration of particle a is 6.0 times that of particle b. particle b takes 2.4 times as long for a rotation as particle a. what is the ratio of the radius of the motion of particle a to that of particle b?

the options are:

5: 1

1: 3

14: 1

1: 1

i'm very confused here because i don't understand how any of these choices can represent the answer. i know the acceleration of a is 6 times greater than b, and b takes 2.4 times longer to to complete a rotation compared to a. but how can i compare the motions, when it doesn't really give me anything to compare it to?
