4 minutes
Step-by-step explanation:
Speed Dating events usually take place in bars, restaurants or nightclubs, in environments with conditions for quiet, relaxed and fun conversation. An average of 20 people of each sex are gathered at the event venue, forming a total of 40 participants, who will meet through 4-minute conversations on average per couple. It may seem like a short time, however, according to research, it is not enough more than 3 minutes for a person to know if there was a "chemistry" between the couple.
