To determine how much more gasoline the person will need, we first need to find out the car’s fuel efficiency in miles per gallon (MPG). Based on the information provided, the car uses 5 gallons of gas to travel 132 miles.
We can calculate the MPG by dividing the distance traveled by the gallons of gas used:
MPG = Distance / Gallons = 132 miles / 5 gallons = 26.4 MPG
Next, to find out how many gallons of gas are needed to travel 300 miles, we can rearrange the formula:
Gallons needed = Distance / MPG = 300 miles / 26.4 MPG ≈ 11.36 gallons
The person currently has 3 gallons of gasoline. Therefore, to find out how much more gas is needed, we subtract the amount of gasoline he already has from the total gallons needed:
Additional gasoline needed = Gallons needed – Current gasoline = 11.36 gallons – 3 gallons ≈ 8.36 gallons
In conclusion, the person will need approximately 8.36 more gallons of gasoline to drive 300 miles.
