That's a crazy gamble!

Three particles $A$ , $B$ and $C$ are on the vertices of an equilateral triangle of side length $8 \ \text{ m}$ . Each of them have a velocity of $5 \text{ m/s}$ . They move in such a way that $A$ tries to approach $B$ , while $B$ tries to approach $C$ and $C$ tries to approach $A$ . Find the time at which all of them will meet each other.

Give your answer to $4$ decimal places.
