It is known that the corresponding numbers of two points a and B on the number axis are 6, - 8 respectively. M, N and P are the three moving points on the number axis. The speed of point m starting from point a is 2 units per second, that of point n starting from point B is three times that of point m, and that of point P starting from the origin is 1 unit per second. (1) if points m, N and P move to the right at the same time, how long does the distance from point P to point m and N equal?

If the time is t (s), then M = 6 + 2T n = - 8 + 6T P = t when t
