Step-by-step explanation:
Given




Required
Determine their next meeting time
First, we need to get their unit rate in minutes per round


Convert 360 seconds to minutes



Divide by 2/2

So, we have:



Next, is to determine the LCM of 18, 6 and 2



Their LCM is:


This means that they will meet 18 minutes after their initial time of departure.
So:
