Odometer

The odometer is driven by the wheel's rotation, whose diameter is 65 cm. After how many rotations the wheel turns counter to the next kilometer?

Correct answer:

n =  489.7

Step-by-step explanation:

D=65 cm m=65:100  m=0.65 m x=1 km m=1 1000  m=1000 m  o=π D=3.1416 0.652.042 m  n=x/o=1000/2.042=489.7
