A girl travels along a straight line, from point A to B at a constant speed, V1​ meters/sec for T seconds. Next, she travels from point B to C along a straight line, at a constant speed ofV2​ meters/sec for another T seconds. BC makes an angle 105° with AB. If CA makes an angle 30° with BC, how much time will she take to travel back from point C to A at a constant speed of V2​ meters/sec, if she travels along a straight line from C to A
