Take a simple model to demonstrate.
Trucks arrive at the rate of 1 every 2 minutes
Processing time is 2 minutes
2 minute delay per truck.
With 200 trucks, the average delay is 2 minutes.

First truck is delayed 4 minutes. The second truck 6 (2 minutes waiting for the first truck to be processed + 4 minutes of its own processing), the third truck 8 (4 minutes waiting for the second truck to be processed + 4 minutes for its own processing)... the nth truck is delayed 2+(2xn) minutes.
With 200 trucks (the 200th truck delayed 402 minutes - over 6 hours) the average delay is over 3 hours.
