A car travels 120.5 miles on 3.5 gallons of gas. If the car's fuel efficiency remains constant, how many miles can it travel on 10 gallons of gas?

To find out how many miles the car can travel on 10 gallons of gas, we first need to calculate its fuel efficiency in miles per gallon (mpg). By dividing the total miles traveled (120.5 miles) by the total gallons used (3.5 gallons), we find the fuel efficiency to be approximately 34.43 mpg. Multiplying this efficiency by the new amount of gas (10 gallons) results in a total distance of about 344.3 miles. So, the car can travel around 344.3 miles on 10 gallons of gas! To check your work, it’s always a good idea to keep an eye on your calculations and units. A common mistake here is confusing miles and gallons or not aligning the units properly. When dealing with ratios, think of it like making a tasty smoothie: if you get the recipe right (miles to gallons) and blend it properly (calculations), you'll end up with a delicious result!
