Many students read scales incorrectly because they assume each division on the scale is one unit.For instance they would look at this scale and read it as 69 mph as it is one division before 70. This is wrong! Always work out what each division means first. On this speedometer 5 divisions mean 10mph. So each division is 2mph. It is pointing at 68mph.

Practice reading scales with this exercise.
