Is there a point P on the number axis, such that PA plus Pb = PC? If it exists, find out the number corresponding to P, but it does not exist. Please explain the reason (3) Under the conditions of (1) (2), point a, B and C begin to move on the number axis. If point a moves to the left at the speed of one unit length per second, and point B and point C move to the right at the speed of four unit lengths per second and nine unit lengths per second respectively, suppose that after T seconds, the distance between point B and point C is expressed as BC, and the distance between point a and point B is ab, Please explain the reason, if not, find out the value!
