Consider the following two queueing systems.

System $1$: An M$/$M$/1$ system with arrival rate of $50$ customers$/$hour and service rate of $60$ customers$/$hour$.$

System $2$: An M$/$M$/3$ system with the same arrival rate of $50$ customers$/$hour and each server working at a rate of $20$ customers$/$hour$.$

What are W and L for each system? If needed, round your answers to two decimal digits.

System $1$ System $2$

Expected number of customers in queue $\%$

Expected time in system $($hours$)$
