Question

design a 5 lane athletic track​

Answer 1

Answer:

If they all started from the same line, then the athletes in the outer lanes would have to run further than the athletes in the inner lanes, because of the semicircles at the top and bottom of the track.

So each lane has to have a special starting position so they all have to run the same distance.
