## At what speed does EPA test highway MPG?

80 mph

Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions.

### How to calculate miles per gallon for 30 Gals?

That means you can go about 300 miles before you have to refill. 30 gal x 10 mpg = 300 miles. Remember MPG= Miles / Gallons so mpg=M/G this time we want Miles= something so we can just multiply both sides by gallons to get rid of the G on the bottom. So G x mpg = Miles.

**Which is higher miles per gallon or miles per litre?**

Miles per gallon (mpg – U.S.), fuel consumption The distance travelled per unit volume of fuel used; for example, kilometres per litre (km/L) or miles per gallon (mpg). In this case, the higher the value, the more economic a vehicle is (the more distance it can travel with a certain volume of fuel). 1 mpg

**How many gallons are in a 100 Mile Drive?**

Take the reciprocal of 18 by dividing one by 18 and get 0.055, which is gallons per mile. Then multiply by 100 by moving the decimal point two places to the left, and you’ll get 5.5 gallons/100 miles.

## Is it better to go from 18 to 50 miles per gallon?

Management professors Richard Larick and Jack Soll’s experiments proved that consumers thought fuel consumption was cut at an even rate as mileage increased. Most survey respondents said going from 34 to 50 mpg saved more gasoline over 10,000 miles than did moving from 18 to 28 mpg. Their website, ” The MPG Illusion ,” lays out the whole issue.

### Do you know the math on miles per gallon?

Measure fuel usage the way the entire rest of the world (including Canada) does: consumption over distance. There, it’s mostly liters per 100 km. Here, it’d be gallons per 100 miles. Do you know all this and just do the math in your head?

Take the reciprocal of 18 by dividing one by 18 and get 0.055, which is gallons per mile. Then multiply by 100 by moving the decimal point two places to the left, and you’ll get 5.5 gallons/100 miles.

**Is it better to replace 10 mpg with 20 mpg?**

But, in fact, that’s exactly backwards. Over any given mileage, replacing a 10-mpg vehicle with one that gets 20 mpg saves five times the gasoline that replacing a 33-mpg vehicle with one that gets 50 does. Don’t believe it? Here’s the math.
