Nancy drove 110 km using 13.5 liters of gas. What was her gas mileage in miles per gallon?

A. 3.47

B. 68.2

C. 19.14

D. 20 The answer is D=20 gallons

110km/13.5liters*3.79l/gal*1mile/1.61km= 110*3.791/(1.62*13.5)= hmmm

check it, not your answer.

3.47

110 km/13.5 L

= 110(0.621371) miles/(13.5(0.264172))
= appr 19.2 mpg

btw, in the metric world, gas consumption is not expressed as km/L, but rather as
L/100 km
So the above would be 12.27 L/100 km
(which is quite poor, I use 8.9 L/100 km on my car)

To find Nancy's gas mileage in miles per gallon, we first need to convert the distance traveled and the amount of gas used into miles and gallons, respectively.

We know that Nancy drove 110 km, so we need to convert this to miles. Since 1 kilometer is approximately 0.621371 miles, we can multiply 110 km by 0.621371 to find the distance in miles.

110 km * 0.621371 = 68.35081 miles (rounded to 5 decimal places)

Now, we need to convert the amount of gas used from liters to gallons. Since 1 liter is approximately 0.264172 gallons, we can divide 13.5 liters by 0.264172 to find the amount of gas in gallons.

13.5 liters / 0.264172 = 51.11602 gallons (rounded to 5 decimal places)

Finally, we can find the gas mileage by dividing the distance traveled (in miles) by the amount of gas used (in gallons).

68.35081 miles / 51.11602 gallons = 1.33764 miles per gallon (rounded to 5 decimal places)

Therefore, Nancy's gas mileage is approximately 1.33764 miles per gallon, which is closest to option A: 3.47.
