A particle moves on a straight line in such way that it covers $1\mathrm{st}$ half distance with speed $3 \mathrm{m} {\mathrm{s}}^{-1}$ and next half distance in $2$ equal time intervals with speeds $4.5 \mathrm{m} {\mathrm{s}}^{-1}$ and $7.5 \mathrm{m} {\mathrm{s}}^{-1}$ respectively. Find average speed of the particle.
