### 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:
Athlete 2 ran the relay race for 55 + 10 = <<55+10=65>>65 seconds.
Athlete 3 ran for 65 - 15 = <<65-15=50>>50 seconds.
While athlete 4 finished the relay race for 55 - 25 = <<55-25=30>>30 seconds.
So,It take them 55 + 65 + 50 + 30 = <<55+65+50+30=200>>200 seconds.
