The answer to "how long it takes two" depends on the context:
- If referring to the cooperative video game "It Takes Two," it takes about 12 to 14 hours to complete the main story, and around 16.5 hours for full completion including extras.
- If referring to two people working together to complete a task, the total time depends on their individual work rates. For example, if two people work together, the time can be calculated by summing their work rates. A sample calculation showed two people completing a task in about 35.4 hours, given their individual times.
- For social context, if the question relates to forming friendships between two people, it is suggested it takes about 40-60 hours to become casual friends and up to 200 hours for close friends.
If a specific context is intended (work, game, social, or other), please clarify for a more precise answer.
