It is possible that it could be sold within 30 minutes.It is also possible that it might not sell at all in the 5 days that you ve listed for.A sale is not guaranteed just because you list your item on eBay.
It all depends on the price, the quality of the item, shipping costs, etc. I ve sold many items on eBay and if I wanted to sell it quick, I offered reduced or free shipping depending on the item.
