A car has a 16-gallon fuel tank.
When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas tank, the driver got on a highway and drove for a while.

How many gallons are left in the tank when the car has traveled the following distances on the highway? (246 miles)

Respuesta :

Answer:

8.2 Gallons

Step-by-step explanation:

Given that the car has a gas mileage of 30 miles per gallon and the driver traveled 246 miles, we can calculate the number of gallons left in the tank like this:

The number of gallons left equals the total distance traveled divided by the miles per gallon:

Number of gallons left = 246 miles / 30 miles per gallon

Number of gallons left ≈ 8.2 gallons

So, when the car has traveled 246 miles on the highway, there are approximately 8.2 gallons left in the tank.

Answer:

7.8 gal

Step-by-step explanation:

we can treat the "30 miles per gallon" as a ratio problem:

[tex]\frac{30 miles}{1 gallon} = \frac{246 miles}{x gallon}[/tex]

x WILL NOT give our answer but rather tells us how many gallons of fuel needs to be used up to drive exactly 246 miles,  it's helpful to know as we can subtract that x value from 16 (the amount of fuel we have originally) and get how many gallons remain AKA our answer!

so let's do it!

cross multiply (butterfly):

30x miles*gallon = 246 miles*gallon

x gallon = (246 miles*gallon)/30 miles

x gallon = 8.2 gallons  <-- how much we use to drive 246 mi

16 - 8.2 = 7.8 gallons <-- remaining
