Answer:
the average time spend is 0.111
Step-by-step explanation:
The computation of the average time spend is as follows;
Arrival rate is
= 210 ÷ 10
= 21 per hour
Now the service rate is
= 60 ÷ service time
= 60 ÷ 2 minutes
= 30 per minute
And, finally the average time spend is
= 1 ÷ (service rate - arrival rate)
= 1 ÷ (30 - 21)
= 0.111
Hence, the average time spend is 0.111
