The speed shown on a car¡¯s speedometer is proportional to the rate of rotation of the tyres.

The variation of the diameter of a tyre as it wears introduces an error in the speed shown on the

speedometer.

A car has new tyres of diameter 600 mm. The speedometer is accurately calibrated for this

diameter.

The tyres wear as shown, with 6 mm of material being removed from the outer surface.

What is the error in the speed shown on the speedometer after this wear has taken place?

A

The speed shown is too high by 1%.

B

The speed shown is too high by 2%.

C

The speed shown is too low by 1%.

D

The speed shown is too low by 2%.
