Less than a second : The process of sperm fertilizing and egg takes less than a second. The sperm penetrates the cell wall of the bag and fertilization is essentially instantaneous. If you're asking how long after intercourse until fertilization occurs that can be anywhere from a few hours to 4-5 days.
