Just a rough guess from the article, it wasn't a short while. I'd say at least a few weeks. Who knows what finally did them in though. A little while without rain could have depleted their water supply. Exposure to the sun could have done it. There wasn't a mention of any makeshift cover. For all we know, a particularly nasty storm could have swept them out to sea. A 1938 report stated that the highest point was 16 feet above low sea level, and nothing is to say that they camped at the highest point. Looking at the island with Google Maps, it appears the sea sweeps across the southern side on a regular basis.
It would be nice to think they only survived for days. It could have been months. With no real supplies, something as simple as a cut could have been fatal.
In any case, they didn't survive. That is very unfortunate, as they could have if they had been found in time.
