Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Candace decides to enter a race. The race is run in 4 segments, with racers eliminated at the end of each segment. 10 racers are eliminated after the first segment. A third of the remaining racers are eliminated after the next section. Half of the remaining racers are eliminated before the last leg of the race. If 100 racers started the race, how many will run in the final section of the race?

### Response:
 Baada ya sehemu ya kwanza, kuna washindani 100 - 10 = <<100-10=90>>90 waliobaki katika mbio.
Baada ya sehemu ya pili, washindani 90 / 3 = <<90/3=30>>30 wanafutwa.
Hii inaacha washindani 90 - 30 = <<90-30=60>>60 wanaoshindana katika sehemu ya tatu ya mbio.
Baada ya sehemu ya tatu, washindani 60 / 2 = <<60/2=30>>30 wanafutwa.
Hii inaacha washindani 60 - 30 = <<60-30=30>>30 watakaoendelea kukimbia katika sehemu ya mwisho ya mbio.
