Final answer:
To find out how many gallons of gasoline would be needed to travel 900 miles, we can use the concept of fuel economy. Fuel economy is a measure of how many miles a vehicle can travel per gallon of gasoline. By dividing the distance traveled by the amount of gasoline used, we can calculate the fuel economy and determine the number of gallons needed for a given distance.
Step-by-step explanation:
To find out how many gallons of gasoline would be needed to travel 900 miles, we can use the concept of fuel economy. Fuel economy is a measure of how many miles a vehicle can travel per gallon of gasoline. In this case, we can calculate the fuel economy by dividing the distance traveled (154 miles) by the amount of gasoline used (5.5 gallons).
So, the fuel economy is 154 miles/5.5 gallons = 28 miles per gallon.
To calculate the number of gallons needed to travel 900 miles, we can use the formula:
Number of gallons = Distance / Fuel economy.
Plugging in the values, we get:
Number of gallons = 900 miles / 28 miles per gallon = 32.14 gallons.
Therefore, the car would need approximately 32.14 gallons of gasoline to travel 900 miles.
