これなら５分と持たずに… (purpose of と particle)


[![伊藤：塔矢は負ける！これなら５分と持たずに](https://i.stack.imgur.com/urbUK.jpg)](https://i.stack.imgur.com/urbUK.jpg)

I understand this sentence as meaning "Touya will lose! At this rate he will
not last 5 minutes" but I am puzzled as to why と is used here

[With a direct
search](https://www.google.com/search?q=%22%E3%81%A8%E6%8C%81%E3%81%9F%E3%81%9A%E3%81%AB%22)
i see that "と持たずに" is not only a used phrase, but it seems to always be used
with time expressions. However I don't know what sort of と this is, and a
phrase like （５分）と持つ doesn't seem to exist. In fact a phrase like 'last 5
minutes' seems to be ５分持つ without any particle, so I am a little lost.

I wondered if I should interpret it as a conditional と, so that the meaning is
something like "five minutes like this and he will not last" but I am pretty
sure that is not right.

Any help would be appreciated.
