Answer:
The distance covered by the car in 12 gallons of fuel is 630 miles.
Step-by-step explanation:
Distance covered by car in 4 gallons of fuel = 210 miles.
Let us use unitary method to find distance covered by car in 1 gallon of fuel.
Distance covered by car in 1 gallon of fuel = 210/4 miles.
Let us use unitary method to find distance covered by car in 12 gallon of fuel.
Distance covered by car in 12 gallons of fuel = (210/4)*12 = 630 miles.
