NORALIE USES 22 GAL OF GAS TO GO 682 MILES.

WHAT ARE THE 2 UNIT RATES SHE MIGHT COMPARE & COMPUTE THEM

I KNOW ONE IS MILES PER GALLON BUT WHAT IS THE OTHER UNIT RATE? LITERS PER KILOMETER? PLEASE HELP

what are the two unit rates that she might compute

mpg is usually used in the USA. km per liter is the rate most often quoted in the rest of the world.

i welly hate math but i have bad grades on my test and homework .So i have to make it better

Yes, you are correct that one possible unit rate is miles per gallon (mpg). To compute this, you divide the total number of miles (682) by the total amount of gas used (22 gallons).

The formula for miles per gallon is: mpg = miles / gallons = 682 miles / 22 gallons ≈ 31 mpg.

Now, let's find the other unit rate you mentioned, which is liters per kilometer (L/km). However, to compute this, we need to convert the given measurements from gallons and miles to liters and kilometers respectively.

Let's start with converting gallons to liters.

1 gallon ≈ 3.78541 liters

So, 22 gallons ≈ 22 * 3.78541 liters ≈ 83.48102 liters (rounded to five decimal places).

Next, let's convert miles to kilometers.

1 mile ≈ 1.60934 kilometers

So, 682 miles ≈ 682 * 1.60934 kilometers ≈ 1097.02988 kilometers (rounded to five decimal places).

Now that we have the values in liters and kilometers, we can calculate the unit rate in liters per kilometer (L/km):

liters per kilometer = liters / kilometers = 83.48102 liters / 1097.02988 kilometers ≈ 0.076 L/km (rounded to three decimal places).

Therefore, the two unit rates in this scenario are approximately 31 mpg (miles per gallon) and 0.076 L/km (liters per kilometer).
