First, we measured what – each lane with a piece of string. First we measured the outside lane and found that that was 50 centimetres, then the third lane which was 49, and so on, and each time it went down a centimetre. So we decided that we would stagger them out a centimetre behind each other.

Peter

So on your diagram they're a centimetre behind?

Lucy

Yeah.

Peter

Can I just have a look at that? Either one will do. Right, have a look at this then.

That was Lucy, Anita's and Marsha's solution to the problem. Anything you notice, any comments, any questions you want to ask? Robert?

Robert

What's the rectangle for?

Lucy

We just wanted to see what the em – if we had a rectangle, how big the whole thing would be if it was like that. It was 62 centimetres but it – we found it had nothing to do with the track.
