As Davey says, it is impossible to say without testing. Depends on (in no particular order) your backup software , your network, your master and media server configuration/hardware, availability of tapes, amount of other backups running ...

Yes, I agree it is difficult to say without testing. But this question is asked to me in an interview. So I have to be ready with this answer. Any help in this regard will be very thankfull.

there is no answer that can be given, none whatsoever

understand that
