A particle moving in a straight line covers half the distance with speed $\displaystyle 6 \mathrm{~m} / \mathrm{s}$. The other half is covered in two equal time intervals with speeds $\displaystyle 9 \mathrm{~m} / \mathrm{s}$ and $\displaystyle 15 \mathrm{~m} / \mathrm{s}$ respectively. The average speed of the particle during the motion is:
