The inside lane in the track is 50m and the outside of the track is 100m

Question

4 lanes are added around the outside of the track shown above. Each lane is 1 meter wide and the lanes are immediately next to each other with no space in between. If Teresa runs once around the outside lane, and Martina runs once around the inside lane, how much further does Teresa run than Martina?

Answer 1

did you start this with "The inside lane in the track is 50m and the outside of the track is 100m" ?

That answers the question as I read it.

Answer 2

Yes I did since I can't put a picture of a track I just wrote down the problem so the question is asking how much further does Teresa run than Martina?
