Robin wants his skateboard to roll as far as possible. What kind of surface would be best for him? Rough concrete Smooth trackWooden trackNone of the above

A smooth track would be the best surface for Robin's skateboard to roll as far as possible. Here's why:

1. Friction: The smooth track would have less friction compared to rough concrete or a wooden track. Friction is a force that opposes motion, so less friction means the skateboard can roll further.

2. Consistency: A smooth track is likely to be more consistent, without the bumps and cracks that can slow a skateboard down on concrete or wood. This consistency helps maintain speed and distance.

3. Material: Tracks are often made of materials designed for speed and smoothness, which would help the skateboard roll further.

So, the answer is "Smooth track".
