Vehicles begin to arrive at a border gate at 06h50 with a deterministic arrival
rate of λ (t) = 5.2 - 0.01t (λ is in vehicles per minute and t in minutes after
06h50). However, the gate opens at 07h00 and serves vehicles at a rate of μµ(t)
=3.3 + 2.4t (with t in minutes after 07h00 and u in vehicles per minute). Once
the service rate reaches 10 vehicles per minute, it stays at that level for the rest
