Luanne's car has a range of 675
miles on one tank of gas.
Her car averages 45
miles per gallon and has already used 2
gallons of gas.
How many gallons of gas, g
, are left in the tank?
Luanne's car has a range of 675 miles on one tank of gas and it has already used 2 gallons of gas.
Since the car averages 45 miles per gallon, Luanne has already traveled 2 * 45 = <<2*45=90>>90 miles.
To find out how many gallons of gas are left in the tank, we need to subtract the miles already traveled from the total range.
So, the car still has 675 - 90 = <<675-90=585>>585 miles of range left.
Since the car averages 45 miles per gallon, it means that for every gallon of gas, Luanne can travel 45 miles.
Therefore, the car has 585 / 45 = <<585/45=13>>13 gallons of gas left.
To find out how many gallons of gas are left in Luanne's car, we can use the formula:
Gas left = Total range - Range already covered
First, let's calculate the range already covered. We know that her car averages 45 miles per gallon, and she has already used 2 gallons of gas:
Range already covered = 2 gallons * 45 miles per gallon = 90 miles
Now, we can calculate the gas left in the tank:
Gas left = 675 miles - 90 miles = 585 miles
Therefore, there are 585 miles left in the tank.
To find the number of gallons of gas left in the tank, we need to subtract the amount of gas already used from the total capacity of the tank.
Given:
Total range on one tank of gas = 675 miles
Average miles per gallon = 45 miles/gallon
Amount of gas already used = 2 gallons
First, let's find the total number of miles the car can cover with a full tank of gas:
Total range = Average miles per gallon * Number of gallons
Total range = 45 miles/gallon * Number of gallons
Since the total range is given as 675 miles, we can set up an equation:
45 miles/gallon * Number of gallons = 675 miles
Now, let's solve for the number of gallons:
Number of gallons = 675 miles / 45 miles/gallon
Number of gallons = 15 gallons
Finally, to find the number of gallons of gas left in the tank, we subtract the amount of gas already used from the total capacity of the tank:
Gas left in the tank = Number of gallons - Amount of gas already used
Gas left in the tank = 15 gallons - 2 gallons
Gas left in the tank = 13 gallons
Therefore, there are 13 gallons of gas left in the tank.
