Make some approximations here to create a base $$

Assume on an average $2$ people $/$car $=$ so that makes it about $25$ million cars

We will not need a recharge for driving less than $300$ miles $$ assume that this is about $50\%$ of the driven cars. So$,$ that makes it about $12$ million cars, rounded down.

The above leaves us with roughly $12$ million cars who will drive more than $300$ miles and will therefore, need a recharge in a publicly available charging network. $($of course, we are assuming all cars in this scenario are EVs!$).$

Use the single server queuing model for the base scenario. Assume that a charge per car takes about $40$ minutes. So$,$ that implies a service rate of $1\mathrm{.}5$ cars per hour i$.$e$.36$ cars per day. Can you design the queuing system with this assumption? $($Show calculations on all the quantitative questions and any associated explanations$)$

If all cars need charging the day before Thanksgiving, how many chargers will we need? $($assume all cars needing charging arrives evenly throughout a $24-$hour period$)$

What are the average wait times and # of cars in line when any car arrives at a charging station?

If I am need this service during that day, what is my chance $($probability$)$ of not having more than $5$ cars in the system when I arrive at the system?

If all cars drive $>300$ miles but across five different starting city$-$destination city pairs, how many chargers will we need? $($assume the total number of cars needing charging is equally split across the five pairs$)$
