Answer :

The distance travelled and the number of rotations of a circular ring moving along a line.

Let the distance travelled be d and the number of rotation be n.

We know,

The distance travelled in one rotation = 2πr

where r is the radius of the circle

so, distance travelled in n rotation =d = 2nπr

We can whatever value we like for n on right side of the above equation. So, n is a variable. But r is a constant, we are considering the movement of a single ring.

Whatever value we give for n, that the value will be multiplied by a constant 2πr. So, d will always be proportional to n.
