After the first segment, there are 100 – 10 = <<100-10=90>>90 racers left in the race.
After the second segment, 90 / 3 = <<90/3=30>>30 racers are eliminated.
This leaves 90 – 30 = <<90-30=60>>60 racers to compete in the third segment.
After the third segment, 60 / 2 = <<60/2=30>>30 more racers are eliminated.
This leaves 60 – 30 = <<60-30=30>>30 racers to run in the final section of the race.
