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

### Instruction:
Four athletes joined a relay race. Athlete 1  ran for 55 seconds, athlete 2 ran 10 seconds more than athlete 1, athlete 3 ran 15 seconds less than athlete 2, and athlete four finished it 25 seconds less than athlete 1. How long, in seconds, did it take them to finish the relay race?

### Response:
 Mwanariadha 2 alikimbia mbio za kurusha kwa sekunde 55 + 10 = 65.
Mwanariadha 3 alikimbia kwa sekunde 65 - 15 = <<65-15=50>>50.
Wakati mwanariadha 4 alimaliza mbio za kurusha kwa sekunde 55 - 25 = <<55-25=30>>30.
Hivyo, iliwachukua sekunde 55 + 65 + 50 + 30 = <<55+65+50+30=200>>200 kumaliza mbio za kurusha.
