Question

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round
of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the
same point and at the same time, and go in the same direction. After how many minutes
will they meet again at the starting point?​

Answer 1

Step-by-step explanation:

LCM of 12 and 18

12 = 2 × 3 ×2

18 = 3 × 3 × 2

LCM = 2 × 3 × 2 × 3

= 36

after 36 minutes they will meet again at starting point
