Explanation / Answer
a.
The throughput rate is 30 buses per hour.
The throughput time is 20/60 = 1/3 hours
TT=WIP/TR
TT*TR=WIP
30*1/3=10
10 buses are traveling to and from the airport.
b.
This reduces the average waiting time, but has no effect on the average traveling time. The average traveling time does not change and will remain 20 min.
