4/5 of 300 = 240
so, the gas used is
60/20 + 240/30
so, the gas used is
60/20 + 240/30
= 4/5 x 300
= 240
-------------------------------------
Meaning, the gas used is...
60/20 + 240/30
= 3 + 8
= 11
∴ 11 gallons of gas were used.
Now, since the car averages 30 miles per gallon on the highway, it will use 8 gallons of gas (240 / 30). And for the city driving of 60 miles, since it averages 20 miles per gallon, it will use 3 gallons (60 / 20).
Adding those together, we get a total of 11 gallons of gas (8 + 3) for the entire 300-mile trip. So, don't forget to bring your clown-sized fuel tank on this journey! 🤡😄🚗
First, let's calculate the distance of each portion of the trip:
Highway driving distance = 4/5 * 300 miles = 240 miles
City driving distance = 1/5 * 300 miles = 60 miles
Now, let's calculate the number of gallons of gas used for each portion of the trip:
For highway driving:
Gallons of gas used = Highway driving distance / Miles per gallon (highway)
= 240 miles / 30 miles per gallon
= 8 gallons
For city driving:
Gallons of gas used = City driving distance / Miles per gallon (city)
= 60 miles / 20 miles per gallon
= 3 gallons
Finally, to find the total gallons of gas used for the entire trip, we add the gallons used for city and highway driving:
Total gallons of gas used = Gallons used for highway driving + Gallons used for city driving
= 8 gallons + 3 gallons
= 11 gallons
Therefore, the car will use 11 gallons of gas on a 300-mile trip if 4/5 of the trip is highway driving and the rest is city driving.
