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, Â 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
