Hauswald 21:21.0
Boulygina 22:04.4
Henkel 22:06.1
Wilhelm 21:11.1
Jonsson 22:05.8
My program produces output:

Zaitseva

Wich i consider to be correct because Henkel will have finish time of 22:06.1 minus 90 sec  and it will make him first at time of his finish.
Where I am wrong?

In the i-th of the following n lines you are given ... the contestant's running time

Not finish time but running time.
