The tachometer indicates:
AThe number of engine revolutions per kilometre travelled.
BThe number of engine revolutions per minute.Correct
CThe number of engine revolutions per metre travelled.
Explanation
The tachometer is the instrument on the dashboard that indicates the engine's rotational speed, measured in revolutions per minute (RPM). This information helps the driver manage gear changes efficiently and avoid excessive engine operating speeds. The other options are incorrect because the number of engine revolutions is not measured based on the distance travelled (whether per metre or per kilometre), but rather based on time (per minute), regardless of the vehicle's speed or the engaged gear.
