Final answer:
To determine the number of times to fill up the tank for a 450-mile trip, the vehicle's fuel efficiency in miles per gallon (mpg) is required. Once known, the total distance is divided by the range per full tank to calculate the needed fill-ups. The substantial additional info provided does not directly answer the question without the car's mpg.
Step-by-step explanation:
The question involves determining how many times a gas tank must be filled up to drive a certain distance. If someone drove 450 miles with 1/4 tank of gas, we need more information about the vehicle's fuel efficiency to calculate the entire tank's mileage. Generally, if one quarter of a tank covers 450 miles, four quarters (a full tank) would cover 1800 miles. This assumes that fuel consumption is consistent and that the car's fuel efficiency does not change with driving conditions or tank level. However, without the exact fuel efficiency of the car in miles per gallon, we cannot provide a definitive answer. Typically, a fuel economy is given (as with the Toyota Prius Hybrid example which gets an average of miles per gallon), and one would use this to calculate the tank's total range and then divide the total distance by the range to find the number of fill-ups required.
