Q: How do I read the tachometer?

How do I read the tachometer?

The tachometer is located on the instrument panel, and tells you how fast your engine is running. The tachometer is a semicircle with a bunch of numbers, which correspond to the speed of your engine, in terms of revolutions per minute (RPM). Whatever number the needle is pointing at, when multiplied by 1,000, is the speed at which your engine is moving (for example, if the tachometer needle is pointing at 3, then your engine is operating at 3,000 RPM).
