I'm going to continue off the number you left off(which is "cuarenta cinco"), Cincuenta, Cincuenta y cinco, Sesenta, Sesenta y cinco, Ochenta, Ochenta y cinco, Noventa, Noventa y cinco, Ciento y Cinco.
I would assume te someone else is asking someone, and then that someone is responding to that someone else. (That made absolutely no sense.)
For this case, we will translate the sentence part by part.
the coach (masculine): El entrenador
interviews: entrevista
the athlete (masculine): a el atleta
In Spanish the word "el" serves to differentiate the word "atleta" from the masculine or feminine gender.
Answer:
You have to say:
El entrenador entrevista a el atleta.
