How many miles does a car travel using .1 of a gallon if it uses .75 of a gallon in 17.4 miles?
It will travel 2.32 miles.
This is a ratio of fuel to miles; what is required is what miles is equal to 0.1 fuel:
Fuel : miles
0.75 : 17.4
0.1 : distance
To find the distance cross multiply (creating an equation as the product of the left diagonal equals the product of the right diagonal) and solve for distance:
0.75 × distance = 17.4 × 0.1
→ distance = 17.4 × 0.1 ÷ 0.75
→ distance = 2.32
A car has a mileage rating of 38 miles per gallon of gasoline How many miles can the car travel on 76.5 liters of gasoline?
This is a two part problem. First, you must determine the number of miles you can travel on one gallon of gas if it takes two gallons to travel 44 miles. This can be solved by dividing the miles driven by the gallons used. In this problem that would be 44/2 or 22 miles per gallon. Next, if you can travel 22 miles on one gallon, you want to determine how many gallons would be…
Find out the total number of miles you will travel. You need to know the number of miles you get per gallon of gas for your particular car. Then divide the miles per gallon into the total miles you will travel. That will tell you how many gallons of gas you will need. It will still be fairly approximate depending on how fast you travel and the conditions of the road.
How many times will you need to fill up for gas going 99.91 miles going 55 miles an hour with a 19 miles per gallon on a 9 gallon tank?
The will depend on the fuel mileage of the vehicle and of the driver. If a vehicle averages 30 miles per gallon of fuel, then multiply 128 miles times 30 ( 3,840 miles) However, if the fuel economy of the vehicle is only 15 miles per gallon, then 15 times 128 would be the distance you could travel ( 1,920 miles).
