On average 3.9 planes arrive at the airport per hour.Assume system V=1.
On average, how many minutes do planes circle theairport waiting for clearance to land?
(Hint: this is the WT. Use WT = V*U*PT. Get U using thesame procedure for the last questsion. The V factor is almostalways assumed to be 1. The procedure is similar to the facepainting example in the lecture.)
