It can go 630 miles because 4 needs to be multiplied by 3 to get 12 and so 210 needs to be multiplied by 3 to get the answer of how far on 12 gallons.

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.

Answer: The distance covered by the car in 12 gallons of fuel is 630 miles.
