45. On a straight path, starting from a point, object A moves with constant acceleration $a$ from rest, and at $t = 2\,\mathrm{s}$, object B starts from the same point and moves with constant acceleration $a = 0.5\,\dfrac{\mathrm{m}}{\mathrm{s}^2}$ from rest. If at $t = 6\,\mathrm{s}$ the two objects meet each other, what is their distance at $t = 10\,\mathrm{s}$ in meters? (1) $4.4$ (2) $8.8$ (3) $13.2$ (4) $24.8$
