Module 6: Measurement

 

In Share 3 you may have noticed that it is important to try to stay within a tolerance when different measuring tools give different readings. In this example, the speed tolerance can be written as km/h because you can legally drive at any speed between 0 and 25 km/h in that area. To make sure that your car is travelling within this speed limit, you could choose the highest measurement and keep this below 25 km/h. This means you would have to slow down the car.
