Another question would also be what’s the difference between wheel speed and vehicle speed?
In: 620
The wheel on the car spins at some speed, say 1000 rpm. The diameter of the wheels is some distance, say 30 inches.
The car measures the rotational speed, is preprogrammed with the diameter, and calculates the final speed.
In this case, the circumference is 30pi inches, and it makes 1000 revolutions per minute, so 30,000pi inches per minute. That’s about 131 inches per second, or 89 mph.
