Answer:

The average time spent waiting in line for each student is 2.25 students.

Explanation:

Use Lq with a single server formula.

λ = Avg arrival rate  = 15 std/hr

μ= Avg server rate (individual server capacity) = 20 std/hr

Μ = # of servers/line (identical capacities)

= λ^{2}/μ(μ- λ)

=15^{2} / 20(20-15)

= 225/100

=2.25 students.
