Ideally, you should be getting about 75-80 miles per charge. If the weather is colder (50 degrees for example) it will be less. If you have the HVAC heater on, it will be even less. If you do spirited driving, it will be even less. You could be getting only 50 miles per charge with those 3 constraints. Maybe worse. If you are getting worse, there might be something wrong with the battery pack. If that is the case, you might want to return the car.
I drive on relatively flat roads, do not use the HVAC but heated seats on occasion, and with my careful manipulation of the go pedal and very mild braking, I get about 250 watts per mile average. I have a 2017 with the larger battery, so I get about 115 miles average per charge.
When the weather warms up, so long as you do not use the A/C and go easy on the go pedal, you might get up to 90 miles per charge. That's not freeway miles though, just around town driving.
Is this your first electric car? It can be a weak point for those who had different expectations from what they are getting from their electric car. And know that even with Teslas people complain about poor range. If you are not happy with the FFE, and you can return it, do so. It is better to have a car you have confidence in than one you feel uneasy about driving too far.
An who knows, maybe Carvana will knock a few thousand off the price so they won't have to take the car back. You never know.
Good Luck
P.S. When you give a value in watts per mile, you are giving an efficiency, like miles per gallon. Like a gas car's mpg, the efficiency varies with speed, road, weather, temperature, driving style, load, tire pressure, etc....
The battery capacity in KWatts is like gallons for the fuel tank. The more KWatts (gallons) available, and the better the efficiency (mpg) , the further you can drive.
