Answer:

3770 mm.

Step-by-step explanation:

The diameter of of the wheels is 60mm, that means the radius is 30mm.

Now for one revolution of the wheels, they cover the distance of $2\pi *30mm=188.5mm.$ on the ground.

For 20 revolutions, the distance covered will be 20 times this.

Thus

$Distance\: covered =188.5*20=\boxed{3770mm}$

Which is our answer.
