Difference of length in track lanes (1 vs 8)

Question

The lanes on the circular outdoor track are one meter wide. By running in the lane
next to the innermost lane, Corey ran extra distance in an eight-lap race. How much?

Answer 1

The inner most lane is 400 meters, while the outer lane 8 is 453.66 meters. so if you were to stay in lanes the whole lap and start from the same starting line, the outer lane would be 53.66 meters longer.
