How much would it cost to drive 54.2 miles in a car that gets 16 miles per gallon and gasoline costs $2.31 per gallon?
54.2/16 * 2.31
$7.82
To calculate the cost of driving a certain distance, you need to determine how many gallons of gasoline will be consumed for that distance and then multiply it by the cost per gallon.
First, divide the distance traveled (54.2 miles) by the car's fuel efficiency (16 miles per gallon) to find the number of gallons consumed:
54.2 miles / 16 miles per gallon = 3.3875 gallons
Next, multiply the number of gallons (3.3875) by the cost of gasoline per gallon ($2.31) to find the total cost:
3.3875 gallons * $2.31 per gallon = $7.83
Therefore, it would cost approximately $7.83 to drive 54.2 miles in a car that gets 16 miles per gallon and with gasoline costing $2.31 per gallon.
