Question

help me answer this plz it is for extra credit

Two balls A and B rotate along a circular track. Ball A makes 2 full rotations in 26 minutes. Ball B makes 5 full rotations in 35 minutes. If they start rotating now from the same point, when will they be at the same starting point again? *

Answer 1

Answer: 91 minutes

Step-by-step explanation:

Ball A) 2/26 = 1 rotation every 13 minutes

Ball B) 5/35 = 1 rotation every 7 minutes

Put them into fraction form.

1/13 and 1/7

LCM of 13 and 7 is 91

After 91 minutes they will be at the same point.
