Answer:
Explanation: In the SIR model , the time to recover depends on several factors ,s
uch as the characteristics of the disease, effectiveness of treatment and the individual's immune response. The variable y is not typically used in SIR , so it is unclear how it relates to the time recover .
In SIR model, the recovery rate is reperesented by " 1/ gamma" Where gamma is a recovery rate . The recovery rate is the inverse of the average duration of the infectious period. So, if the infectious period is 5 , then the recovery rate would be 1/5 or 0.2.
