求翻译：是利用磁力感应车轮的转速（就是每分钟走了几圈），然后将转速乘以车轮的周长（就是车轮在地上走一圈是多远）再除以时间那就是你的平均速度了是什么意思？

(That is, every minute walk a few laps), then the speed multiplied by the circumference of the wheels (wheels on the ground you walk is how far) and then divided by the time it is your average speed is the use of the wheel speed of magnetic induction

Using magnetic induction of the wheel speed (that is go a few minutes each) and then multiplied by the speed of the wheel circumference wheel on the ground (that is walking distance) is divided by the time that the average speed is what you have

Is the use of magnetic induction speed of the wheel (that is, every minute a few rings), and then speed multiplied by the circumference of a wheel (that is, the wheels on the ground in a circle is very far) and then divided by the time it is your average speed

Was (is each minute walked several) using the magnetic induction wheel rotational speed, then was multiplied by the rotational speed the wheel perimeter (is wheel in ground walks is far) divides time that is again your average velocity
