To find the average number of people in the system, we need to add the number of people being served and in line and divide by the number of periods. The total number of people being served and in line is 390 + 250 + 90 + 210 + 10 = 950. The number of periods is 29 (the total time in minutes divided by the service time of 1 minute per person). Therefore, the average number of people in the system is 950/29 ≈ 32.76 or 1.646 rounded to three decimal places. Thus, the best choice is B.
