Answer:
36 minutes
Step-by-step explanation:
Number of minutes after which they will meet at the starting point is the LCM of their speeds.
Given: Speeds are 18 minutes and 12 minutes per round respectively.
18 = 2 × 3 × 3
12 = 2 × 2 × 3
Thus, LCM = 2 × 2 × 3 × 3 = 36 minutes.
Therefore, ANS = 36 minutes
