Answer:
Even if a person doesn't show symptoms, they can still have it.
Step-by-step explanation:
That's the problem.
Even if you think everyone isn't sick, they very well could be, and because there is no vaccine and it spreads so quickly, there's a chance that all the people in that group could get it.
Perimeter = 2 1/8 + 3 1/2 + 2 1/2 = 7 (1 + 4 + 4)/8 = 7 9/8 = 8 1/8
In order to calculate, you need to find their LCM
LCM of 5,6 and 8 is equal to 120
So, That time will be 120 sec = 2 min.
In short, Your Final Answer would be 2 min.
Hope this helps!
