Final answer:
The estimated cost in gas for a cross-country drive across the United States, with the parameters provided (3000 miles, $2.00 per gallon, 25 mpg), is approximately $240. This estimate assumes consistent gas prices and driving conditions.
Step-by-step explanation:
To estimate the cost of gas for a cross-country drive across the United States with the given parameters, we can use the following mathematical calculation:
- Determine the total miles to be driven: 3000 miles (width of the U.S.).
- Calculate the number of gallons of gas needed by dividing the total miles by the car's fuel efficiency: 3000 miles ÷ 25 miles per gallon = 120 gallons.
- Compute the total cost by multiplying the number of gallons needed by the cost per gallon: 120 gallons × $2.00 per gallon = $240.
Therefore, the estimated cost for gas for the trip is $240.
It's important to note that this is a simplified calculation that assumes consistent fuel efficiency and gas price across the entire trip. Real-life factors such as changes in terrain, traffic conditions, and fuel prices can affect the actual cost.
