Answer:

Explanation:

Amps refers to the electrical current.

We have to find the electrical current when the car has a 12-volt battery and the engine has a resistance of 0.22 ohms.

The relation between these magnitudes is

V=I* R

Where
is the voltage,
is the electrical current and
the resistance.

We know that
V=12; R=0.22 . Replacing these values in the formula and solving for

$V=I* R\\(V)/(R)=I\\ I=(12)/(0.22)\\ I\approx 54.54 amp$

Therefore, the answer is around 54.54 amps.
