To solve this problem, we first need to understand the concept of fuel efficiency which is usually measured in miles per gallon (mpg). In this instant, let's take the fuel efficiency as 25 miles per gallon. To find out how far you can travel with 3.5 gallons of gas, you need to multiply the volume of gas you have by the distance you can travel on a single gallon.
So, if your car's fuel efficiency is 25 miles per gallon, and you know that you have 3.5 gallons of gas, the calculation you need to make is as follows:
Distance = Volume of gas * Fuel Efficiency
Fuel Efficiency = 25 miles per gallon,
Volume = 3.5 gallons
Distance = 3.5 gallons * 25 miles per gallon
Following this calculation, you'll find that the 3.5 gallons of gas will allow you to travel .5 miles. This calculation means that with a fuel efficiency of 25 miles per gallon, and 3.5 gallons of gas, you can travel a distance of
Answer: 87.5 miles.
