So for this, we can write that the service rate, let's say that mu, is equal to 60 over 2, which is 30 per hour.
00:20
And for the arrival rate, which we can make lambda, is equal to 4 times 60 over 10, which is going to be equal to 24 per hour.
00:40
So for a, we want to find the average time occurs in the system.
00:49
So what we would do is we'd find 1 over mu minus lambda, which is going to be equal to 1 over 30 minus 24, which is equal to 0 .17.
01:07
Hours.
01:11
For b, i want to find the average number of cars in the system.
01:16
So we are going to do lambda over mu minus lambda, which is going to be equal to 24 over 30 minus 24, over 30 minus 24, which is going to be equal to four cars.
01:35
For c, we want to find the average time cars spend waiting to receive service, which is going to be lambda over mu minus lambda times mu, which will end up being 24 over 30 minus 24 times 30, which is equal to 0 .13 hours...
