Final answer:
The correct conversion factor for a car that gets 50 miles per gallon and has 5 gallons of gas is 250 miles / 1 gallon, which is not listed among the provided options.
Step-by-step explanation:
The question is about determining the correct conversion factor for the amount of distance a car can travel with a given amount of gasoline. The car in question gets 50 miles per gallon and has 5 gallons of gas. To find the total distance the car can travel, we multiply the miles per gallon by the number of gallons. So, the conversion factor would be 50 miles/gallon × 5 gallons, which equals 250 miles. Therefore, none of the options provided (a, b, c, d) correctly represent the total distance the car can travel with 5 gallons of gas. The correct conversion factor should be 250 miles / 1 gallon, which isn't one of the options given in the question.
