Suppose
that A, B, and C are 3 points in a plane, such that AB = AC = BC = 1. At each point in
time, A is moving toward B, B is moving toward C, and C is moving toward A, all with speed
v = 50.
This is what the movement will look like. The red curve
represents the path of point A, the green curve - the path of point B, the blue curve -
the path of point C.
At what time(t) will all the points be the same point? Express your answer
to the third decimal place.
