Find the rate in which both balls make one full rotation around the track.
Ball A:
![120 / 4 = 30](https://tex.z-dn.net/?f=120%20%2F%204%20%3D%2030)
It takes 30 seconds for Ball A to make a full rotation.
Ball B:
![60 / 3 = 20](https://tex.z-dn.net/?f=60%20%2F%203%20%3D%2020)
It takes 20 seconds for Ball B to make a full rotation.
Find the least common multiple of 20 and 30 to find the time at which they'll meet.
Multiples of 20: {20,40,60}
Multiples of 30: {30,60}
60 is the least common multiple of both 20 and 30.
The balls will meet again at
60 seconds.
