factors:

- you are on a 100 meter track

- person A walks towards you

- person A takes a 1 meter step every second

- track grows longer as person A walks

- track grows 1 meter for every 100 meters every second

- after 10 seconds, the walker has taken 10 steps, but the remaining 89 meters has grown so that he still has 98 meters from you

- another 10 seconds and he still is almost 97 meters away

- It will take him 460 seconds to reach you; during this time, the track is stretched so that it's now 10000 meters long.

My questions are:

- I don't understand how he becomes the result '98 meters away from you'. In my reasoning, track grows up to 101 meters because the track itself is already 100 meters.

Perhaps I'm wrong?

- What exactly does he mean by "the track grows 1 meter for every 100 meters every second"?

- How does he conclude that person A needs 460 seconds to reach me?

- How does he conclude that the track has grown 10000 meters long?

Many thanks for your cooperation.

Treval
