547 mi / 19 gal = 28.8 miles per gallon.
The idea is to divide the number of miles by the number of gallons. That gives you a certain number of "miles per gallons".
The number of miles you can drive on 16 gallons of gas depends on your vehicle's fuel efficiency. If your car gets an average of 25 miles per gallon, you could drive about 400 miles on 16 gallons of gas.
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
Not enough information. Basically, you need to divide the number of miles by the number of gallons.
mpg means "miles per gallon" which is calculated as the distance travelled in miles divided by the fuel used in gallons. mpg = miles/gallons → mpg × gallons = miles → gallons = miles/mpg ie if you know the average mpg for your vehicle over a distance (in miles), then the amount of fuel used (in gallons) can be calculated by dividing the distance by the (average) mpg.
Your average for this trip is 21.5 mpg
Me? 109 miles/27 = 4.037 gallons ============== That is an average.
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
You can divide the number of miles by the number of gallons, to get miles per gallon.Or you can divide the other way (the number of gallons by the number of miles), to get gallons per mile. Each of the above will be a unit rate, but in this particular case, it is more common to calculate miles per gallon.
You first need to know what your average speed is to determine how many miles have been traveled

It is about 1000 miles between the two cities. You need to take the 1000 distance and divide it by your highway miles per gallon average - this will give you the number of gallons of gas it will take to drive between the 2 cities. Then divide the number of gallons by the size of your gas tank in gallons. Here is an example: 1000 miles divided by 20 miles per gallon = 50 gallons of gas. 50 gallons divided by a 10 gallon fuel tank = 5 tanks of gas.
